Can't set up gamepad for mobile version (Terraria)

I wanted to play a joystick in mobile terraria, connected it, the game sees it. Where you can select the gamepad, the virtual button is still displayed, and here you can configure it, but not completely, since the sticks are not bound and the cross, too, and on the button where you can select the gamepad, not a single button is bound at all, although in other games everything works fine. Please help me set up my gamepad.
