Picade Max Batocera Joysticks

Hi - I know Batocera isn’t the preferred gaming distribution for Picade Max but I’ve got a simple question. I boot off my SD card and everything looks great. When in hit a button it asks me to configure input and I move the left joystick up, down, left and right but when I exit I can’t move around the menus.

It’s seemed simple but have I missed a trick?

sdl2-jstest is seeing the stick at +/- 127 on the up and left axis.

Thanks.

Garan.
