LButton bind is broken in 0.4.1.4

[ZizzyZizzy]

RDR in Ryujinx 1.1.998.

I'm trying to bind "fire/punch" to the LButton. When I right-click to aim and then press the left mouse button, it triggers two other actions - holding Tab to open the weapon wheel, and crouch. See screenshot for other binds, all working fine.

I had to change my LButton to MButton just to play the game and be able to fire weapons.
