Controls not working with Gamecube Emulator

Hi I installed Bazzite on my ROG Ally X to run Steam OS. I also installed Emudeck, but when I try to play GameCube games the Start button does not register. I made sure its mapped when I press the start button on my Ally X but it does not register. Has anyone had similar problems? When I run Primehack then the game it seems to work but some buttons aren’t mapped correctly and the screen is really small.

Are they mapped in the emulator under controller settings?
