That really sucks, but I don't think the entry is junk, since it looks like those audio CD's exist.
They don't seem to have incorrect fingerprints or anything like that, did your tracks get matched to that release using the 'Lookup' button?
But before clicking 'save' those fields must have been pretty dark red if your existing tags were very different... which is a pretty big warning flag. Picard uses algorithms to try and guess what you want it to do/ what to match, so it's not always perfect. Bulk tagging on files that haven't been matched before is tricky, and I would either back them up first or:
But anyway, sorry to hear, if there's something specific that you think needs to be changed or addressed post your ideas!
