Hello, I'm trying to rename all episodes of Days Of Our Lives from 1984 to 2010 so that they are recognized and named correctly in Plex. I installed FileBot on my Mac, but I haven't had any success with the renaming process. The problem is that some years are missing from the available databases ...

I think you can can SHIFT-CLICK <database> to force manual input and manual selection. That'll allow you to override previously remembered selections.
