Oculus Rift controller triggering gamepad input

When I use the oculus controller certain inputs mapped to the gamepad also get triggered. For example if I press A on the right oculus controller the A button on my xbox controller gets triggered and when I press the grab trigger the RB on the xbox controller gets triggered.

I'm using the oculus rift cv1 , unity 2019 and the old input system.

Any help how to solve this issue?
