DS4 dpad not recognized ?

[hitmaker]

Dpad for DS4 controller does not seem to be recognized, can't configure it either in controller settings. All other buttons are working fine.
Tried 2 different DS4 controllers, same result.
Installed latest recalbox 6.0 on RPI3B (no external bluetooth dongle)

Is this a known bug or am I missing something ?
Dpad was working fine before on recalbox 4.1.

Any help would be appreciated, thanks.

@hitmaker If you use the joysticks on PS4, you need to reset them first. Another possible solution in the emulationstation control setting is to "forget" the already paired controls (I can not remember the right term in English now, and the translator may affect the translation).
