Yes all my Fanatec peripherals are up to date.
Here is the QSG showing the v2 button maps for PC.

Some controls are locked to game menu navigation and cannot be remapped. Otherwise the game will behave unexpectedly.
If you hit this error it is simply that the control cannot be mapped as it would conflict with a menu navigation control.
As before if you could show video of which controls you are trying to remap and what to it might be helpful.
im afraid I have the v2.5 so my mappings are slightly different. Editing the actionmaps require that you save a copy as updating or verifying / reinstalling game files will overwrite your changes.
Alternate solutions are to rewire your controller, eg I use the clutch for a brake on G923 pedals and swapped the spring and board connectors around to save changing or remapping from default.
