XZ doesnt load all solid state drive folders from RB (but all other decks do)

Hi all, 

Using a 32gb partitioned SSD fat32

Exporting from RB has worked for 1 year flawlessly for ANY CDJ I have tried so far, and also Denons. 

It will not load files properly on my XZ
It loads the files properly in my CDJ2k NX2's, it loads on 3000s, it loads on CDJ 1000s. all tested. 

but not the XZ. 

Any thoughts?
