Hi! I’ve seen this problem once before, but don’t know why it does that yet.
Can you upload your Lexicon database, from the Help menu?
And also your current Rekordbox database file? You can find it here Lexicon with Rekordbox 6 write support and you can upload with this link.
I’ll try and look at it as soon as I can. Not sure if I can release a fix for it in time, but I can probably figure out why it’s doing that and give you some kind of solution (but no promises).
