This is a know problem that usually acquires when movie title, original title or year in filmography do not match the ones in the movie record.
Could you elaborate? There are a number of issues around maintaining filmographies, and I'm not sure where this fits in.
Title is meant to be whatever the user wants it to be, so surely that doesn't cause a mismatch. On the other hand, if
Original title is not downloaded and properly maintained, I can see how that might mess things up. I'm not sure if this is one of them, but I find I have fewer problems with filmographies by
not setting
Merge filmography (at
Preferences - Plugins). Might that be a "solution" in this case?
