I often get this with canned tomatoes. As long as the lid seals, it should be fine.but it appears a tiny bit of sauce creeped out at some point. I took off my rings this AM & they were a little stuck. You can see the sauce on the lids & rings. All of the lids did seal though. I also cleaned each rim & top of jar before putting tops on. I did not over or undertighten either (I think). Is this ok?
After the jars cool, I wipe them down thoroughly remove any residue, and then wipe down again with a paper towel dampened with distilled vinegar.
