Does the back of the box say anything about the dub? That's honestly my first check before I even hand over my three bucks. If it lists a bunch of alternate languages or says "unrated" or has some weird runtime that doesn't match the normal one, that's usually a sign there's a goofier version floating around. Also flip it over and look for typos in the summary, because a sloppy release is way more likely to be the funny bad one. If the cover looks too clean and normal, it's probably just regular boring bad.

Went through almost the same thing last year and it was a mess. Moved about 800 people over on a Thursday and the sync glitch sent the welcome email three times to half the list. Got 60 unsubscribes in one day and a handful of nasty replies asking if we were broken. The worst part was the tool's own help docs told me the import was "instant," which it was not. Took their support two days to admit the tags duplicated on their end.
