Controlls interference

So on my Ps5 im not sure if this is the issue on other platforms as well.

When i set up my controls for the full controls and set up different controls on mouse controls (obviously), for some reason when i then lets say use my stick to move the cursor around it starts spinning my plane.

And when i checked my setting on full controls i realised it took the Input from there. Meaning movement controls for the full controls start to overlap with my movement controls for the mouse controls.

I would like to add a video because pictures cant show but this is not possible sadly

I hope you can somehow fix this if its a bug or via. A setting where you can completely separate those two controls

Would be greatly appreciated and i hope for a reply as soon as you need more information or have found a way to fix this

Id be glad to be kept updated if in any way possible and wish you all a good morning/evening/night
