USB Slot 1 not reading ok in slot 2

Just got my new 8k need some advice what I’m doing wrong peeps. I have loaded a few tracks from engine onto a fat32 formatted stick. It reads perfectly in slot 2 but not recognised in slot 1 any clues?

I have a stick with mp3 tunes on and it reads in both slots.

Have you contacted Tech Support yet?

It’s a brand new machine so not happy

Hi @Uk79mod it might be a faulty controller, have you contacted Tech Support?
