Mayflash problem

I bought a Mayflash PCB a while back and only just set it up
Everything is working ok except that my start / select buttons wont work in SF4 on PC.
when I check the controller properties, the start / select buttons are assigned to button 9 / 10 which is what it should be I believe.

Does anyone else have this problem and if so is there some kind of fix for it?
I tried looking in search but couldn’t find anything.
