Playlist active sort options not changing

Hi,

I have recently bought a new USB for music and the 'sort playlist by' options aren't changing. I want to sort by KEY, but after moving it to the active column it has no effect when I plug into my CDJ (900).

I have changed this both in preferences and on the USB under devices in the side bar.

Note that other, older USB's with the sort playlist by KEY still working appear to have the same settings as the new USB when I plug them into rekordbox.

Thanks
