Proton not detcecting Brook PS+Audio controller correctly

Please excuse me if I create the wrong issue or if everyting sounds confusing...

As I installed proton and test a custom build controller using a Brook PS+ audio, I see that some of the action buttons (not the directional inputs, but the ABXY buttons, shoulder buttons, and trigger buttons) are not recognized by the game.

In the other hand, I can see that the system is recognizing the controller without any issue and detects all inputs without any problem.

Is this an errror form my configuration or is Proton/wine not detecting my controller correctly?

System specifications

Kernel: 5.15.65-1-MANJARO 
Game: Guilty Gear Accent Core Plus R
Steam Game ID: 348550
Proton version: 5.13-6
Wine version: 7.16 (Staging)
Controller: Brook PS4+ Audio Fighting Board Fw 1.9

The report names no source files, tests, or entry points. Start by reproducing the controller behavior with Guilty Gear Accent Core Plus R on Proton 5.13-6, then compare the system's recognized inputs with those available in-game. Done means the ABXY, shoulder, and trigger buttons are detected correctly, or the report includes enough logs to identify a configuration or Proton issue.
