RekordBox albums not sorting by Track Number over Link? USB is fine

Hi. I have a pair of XDJ 1000's.

When I export my collection to a USB, everything is replicated perfectly on the XDJ.

But if I plug my MacBook in to the pro dj link, and choose "RekordBox" on the XDJ, this is where things go wrong.

My albums are sorted correctly, but the tracks within the albums are a mess. They are not sorted as Track 1, 2, 3, 4. More like Track 8, 2, 3, 6, 1....

I've Tried:

• Press "Menu" > "Sort by: Default"

-Press "Menu" > "Sort by: Album"

Nothing fixes it.

My tracks are correctly labelled within RB (I've given each track in each album a track number (usually 1 - 10)).

I hope I can get some help. Thank you.
