Corrupted images are duplicates

I have found many "deleted or corrupted images" in a session.
It may have happened since upgrade to V9.0 (or 9.1, I don't remember)
However they appear as duplicates of normal images, with the same filename.
A database and a session check showed errors but did not correct them.
I uninstalled V8 and deleted "settings82" and "settings90"
The "corrupted images" are gone... 😂
