Problem with saving track rating from controller

$3500 I spent on this thing and I can't even get a response on your support forums for an issue a week later...

Well, it would help to know a bit more...

- what controller / player are you using?
- which firmware version is installed on it?
- what version of rekordbox?
- are you using the Sync Manager or are you right-clicking on the USB drive and selecting "Update collection"?

Well then ask...

XDJ XZ 
Latest firmware 
Latest version of RB (6.5.1)
Yes i'm using the sync manager with all playlists selected on both sides.

Instead of the sync manager, right-click on the USB drive and select "Update collection."

"Instead of the sync manager, right-click on the USB drive and select "Update collection"

Makes absolutely zero difference because when the USB is loaded into the PC and I check the rating on the USB in rekordbox in devices, it hasnt been stored from the XZ. It's blank.

Also, the sort order doesn't work when it's been configured in devices. I've told rekordbox about 10 times to sort via 'recently added' and it makes zero difference when the USB is then loaded into the XZ. It just continues to sort by Artist.

by process of elimination, I've found that the ratings are saving to the USB. If I save a track's rating that doesn't have any rating yet, eject the USB from the controller, and then plug it back into the controller, the controller picks up all the saved ratings I've just made. It's only when I plug the USB into RB that it's not recognizing the saved ratings. I tried the method mentioned but it does nothing because it's not recognizing any new saved ratings on the USB.
This has to be a RB issue.
