MAJOR bug in 23.5 Multitrack — edits shifted by fractions of a second on reopen

In the multitrack view, I've got a simple interview session with two MP3s and I've been carefully editing out ums/uhs/etc. But when I close the session and re-open Audition, sometimes, some of those edits seem to have been nudged by fractions of a second, ruining what had been smooth transitions before I closed the app. This does not affect every clip, and it seems the only way to fix it would be to manually check every transition every time the app is opened, which is not feasible. I am going to try installing an older version of Audition.
