Interesting. I've always used 'Delete other formats', so I never tested Auto-Convert with that turned off. But I see the same behavior with it off.
FFDL calls the 'auto_convert_auto_add()' method on calibre's 'Convert Books' action--this is the same as calibre's built-in 'auto convert on add' feature uses. Looking at the source for it, sure enough, it only converts if the default target format isn't there.
After reviewing the calibre code, I think the best course is to add code in FFDL to remove the target format when 'auto convert' is turned on.
Attached is a new test version with that change.
Linwe, thanks for helping figure this out.
