iTunes Playlists + Rekordbox Performance Mode

 I'm not sure what happened in the last 48 hours, but suddenly my iTunes library doesn't sync properly when I'm in Performance mode. It worked fine for two years and now it will only play nice if I first go to Export mode and use the Sync manager (which I've never had to do before). The only other thing that might have changed in the last week is that I removed trials of Lyric and Video.

 I know that there are other posts with similar issues, but many are old and don't seem to have an answer except a blame game towards Apple. Considering that Export mode can read the library just fine, I firmly believe this is Pioneer issue.

Any ideas how I can get my library back without needing to run Export Sync Manager?

iTunes version: 12.7.5.9

OSX: 10.13.5

Rekordbox: 5.3.0
