Handbrake problems Fanatec V2.5 + Gt3 Mclaren wheel

What do I have to do to get the hand brake to work.

Currently I have handbrake connected to V3 pedals, and pedals connected to base.

When I go in to controls, there is already a preset for the GT3 wheel or the V2.5 base, neither has the handbrake mapped by default. It is mapped to a button. I cant click on it to configure.

Only thing I can do is co into custom mapping. But as soon as I click on handbrake to map, it already says buttom 37. As if this button is being pressed all the time. I un plug the hand brake, and click to bind then it puts axis 7 automatically. Whats going on.

Can they not just let us edit the default configs for easiness, or atleast have a copy over function to custom so you dont have to go over every button and axis

Update on this issue:

This only happens with my GT3 wheel connected, if I connect my Forza wheel with Xbox hub, then I can go in and map custom controls.

As I have been having issues with my GT3 McLaren wheel, Miss shifts and double shifts. Paddle problem, I am RMA’ing it back to Fanatec. so I am putting it down to a faulty rim. Hopefully Fanatec will fix or replace it. I think I have proved to them it is not a firmware issue with the Gear paddles miss shifting.
