5.2.3 issues with Browse

Hi I’m having an issue with the browse in 5.2.3. When using a DDJ XP1 if I press the rotary knob down to go back from inside a playlist to the list on the left of the screen the browser freezes. I can’t go up down in or out. Using CDJ900’s in HID mode if I press back too many times the screen on the cdj goes blank and it’s frozen on the computer. If I use the mouse to select a track or playlist it comes back to life. I’ve just reinstalled 5.2.2 and the browse function is working perfectly.
