Prime 4 issues serato and no track playback?

Hi guys was hoping someone could shed some light. My prime 4 is running v 1.52 and my serato is the newes version. When I plug my laptop into the prime 4 and put it in computer mode I’m getting my library from serato show up but I can’t control anything via the prime 4. I can drag and drop songs on my laptop and play on laptop and it comes out of my headphones plugged into prime 4. Also my prime 4 doesn’t seem to let me preview tracks before playing them the headphone icon does not appear help!!

In serato toggle to internal mode
