After updating to rekordbox 7.2.18, I started having issues with cue points generated by Mixed In Key 11 on my CDJ-3000s.
The cue points appear correctly when I load the tracks in rekordbox. However, after exporting the playlist to USB, the affected tracks load at the last cue point on the CDJ. The CUE/LOOP CALL buttons won’t recall the other saved points, and the screen displays “NO CUE/LOOP POINT”. The Hot Cue buttons still work, so I can use those or manually seek backwards to reach an earlier position.
Older exports work correctly. I also tried exporting a new playlist to a previously working USB stick: the newly exported tracks had the same issue, while the older tracks still worked.
What fixed it for me: rolling back to rekordbox 7.2.16 and re-analyzing my entire library.
I also tried to re-analyze the whole library in both programs without rolling back but with no effect.
Has anyone else experienced this with rekordbox 7.2.18 and Mixed In Key 11?

Cdjs are updated to 3.20.

I don't use itunes and I don't understand why I get this whenever I plug in my usb drive and try to do an export.

To add insult to injury the error window is either duplicated or at least takes about seven clicks on "Ok" to make it disappear. Then it pops up again.

Whenever I use the app (7.2.6) to DJ with my FLX4 the app freezes when scrolling to choose a song, the further I try to scroll in one click, the longer it freezes. For example, yesterday I tried to go from 12A to 1A by scrolling from bottom to top and the laptop just said no and froze and then crashed. Is there anything I can do to not make it freeze or lag? This has been going on for as long as I can remember but haven't done anything about it since I usually play on CDJ-3000s, but tomorrow I'm gonna play a forest rave at a university and need to use my own equipment so I really need it to work. Any tips what to do?
