Joystick button menu control assignments - go away!

When I’m in the menus, my joystick (TCA Sidestick Airbus) buttons seems to be assigned to menu controls… this is annoying me. Particularly as I’m regularly changing assignments and pressing buttons will suddenly jump me out of the Controls menu.

I’m struggling to work out what’s going on… I get “[joystick button 1] validate” or “[joystick button 12] Reset” flash up at the bottom of the screen when I press buttons, and this varies depending on what menu I’m in.

I cant find these assignments anywhere in controls options.

How can I disable this? What am I missing?
