Honestly I wouldn't worry about them. Jars often seal and release and seal again during processing. Assuming you used and approved recipe with sufficient vinegar they should still be safe. I'd just mark those jars and use them first.

As to the "basket" issues I have difficulty picturing them falling through the holes but then I never use the jar rack anyway. My jars all go in and come out with the jar lifter one at a time.

Judy, the half pints slip through the wires on my jar rack too. Like Dave, my jars go in and come out with the jar lifter, I'm just not good at submerging those jars, especially the small ones, with the rack. The only purpose for the rack in my canner is to keep those jars up off the bottom of the pot!

I don't bother with those jar racks with handles anymore. Just use a cake cooling rack on the bottom of the pot. I think less hassle getting jar out and less chance of a steam burn using the jar lifter

Okay well that clears a lot up! Thanks everyone!! Those racks stink and I've been using them for years never realizing that I had options. My new one is very flimsy and doesn't feel safe, even more flimsy than my old one, so I'm glad to learn I don't need to use one.

So from what I'm understanding I can put the jars in and out with the jar lifter - and I need to elevate the jars off the bottom of the pot with some sort of rack, allowing the water to circulate underneath the jars. What's interesting is my new Norpro canning rack doesn't elevate the jars - it's just wire sitting right on the bottom of the pot.
