It depends on the cause and severity. But frame TBC can correct this, yes.
Keyword = "can", not will.

So more or less there’s nothing I can do about this or the VCR has to be looked at???

I don't see where that assertion was made. It could be the baked tape image, or the signal, or the VCR, or capture device.

Because I’ve had this unit for a few months now and never noticed it doing this before. This is why I’m bringing this to everyone’s attention.

Realize that "never noticed it" means nothing. Many people overlook issues until they don't. That's just human nature. You could not notice something for months, then get irritated. The brain sometimes has a long lag, long delay, to acknowledge issues.
So, for that reason, the VCR should not be eliminated. Though as per above, nothing really zeroed in on it either, other issues are more likely.

Leaning more towards probably nothing that can be done. Just watched about a half hour of a tape with the TBC turned off and noticed nothing so more than likely the issue lies with the line TBC. Hopefully the Frame TBC I’ll end up using may improve this. Probably not when it’s mentioned that most of the TBC’s that might improve it aren’t recommended anyway.

The line TBC inside VCR isn't 100% perfect. That's NOT a reason to not use it, but rather understand it won't work well 100% of the time. I may fail with some tapes, though it will be a tiny minority (maybe 5% at very most?). Anything more, and it is a VCR issue.
This is where external line TBC is needed, such as ES10/15, though some other devices have various qualities at times (more niche, weaker or different, interesting).

I don't think it's a flaw, or a limitation. But rather the tape issues fall outside of the median bounds of the device. Some errors get more fringe. Attempting to correct a fringe can knock it away from effectiveness from the median. If the TBC was adjustable, then it could probably be tweaked to address this. Or if it could be tweaked, and still failed, then maybe a flaw. But as it exists, I don't think it's fair to call it a flaw.

The external TBC units can help reduce it a bit in some cases but only to a degree. For tapes with a lot of jumping something like a panasonic dvd-recorder for the TBC function might work better.
Of course if the tape path is misaligned or there are other problems with the deck, that can make things worse.

All correct, of course. I'd add that even ES10/15 type can fail on severe errors (including errors that don't "look that severe" but are signal-wise; visual != signal)_

Yep. Posterization, luma, AGC, whole list is quality hits. It's great for net improvements. But sometimes you don't get that net gain, and just further harm the image.

Here’s a new problem. I get zero signal when trying to use S-Video with this unit. Tried two different cables with two different DVD recorders and no signal whatsoever. Composite works. Tested S-Video with one of the recorders with my Panasonic AG1980 just incase the cables were bad. One S-video output gave me no signal, the other did. So the problem most likely lies with the JVC. Any thoughts???

To me, you seem to be rushing from one issue to another, in a panic. You need to slow down, read.
For example, that last TBC "issue" wasn't an issue at all, but rather user error, as a feature (genlock) was turned on. Genlock isn't TBC, and it can screw with the signal. The TBC is fine. However, we're now pivoting to a different TBC(ish) that you may find more useful for your situation, so the outcome of your mistake is a happy accident. So that's a win. Take it. However, others may not end happy.
You've mentioned quite a few VCRs and DVD recorders. Is that all random buys from eBay? And I'd assume hasty buys? As I've mentioned many times, eBay is a video dumping ground now. I'd used eBay since the 90s, and bought video gear into the early 10s (before my health issues). I look at eBay now, even the late 10s, and am aghast at all the crap on their. Damaged, broken, or lied about ("working" and "tested" = too often blatantly obvious nonsense). You have to be savvy about eBay, don't be a victim. And I'm telling you that even trying to be savvy there is now almost impossible. Not just video gear, but other areas like photo or hobby collecting.
So sssssllllloooowwwww down.
Be a scientist here. Diligent, process of eliminations.
