Gamepad mode (How to?) and on Keyboard mode some Buttons do not work (Select wired to 1/4 and Start wired to 1UP)

I have bought my Picade Arcade a few days ago and managed to build it without any issues.
All buttons single button is functionnal in Retropie. Just in Retropie.
I can map all the keys. BUT As soon as I start any emulator. The select and start stop working!
As by default the picade was recognized as a keyboard… I started reading the forums.
I have (after a LONG search, because i am not linux expert) finally managed to update to firmware picade_gamepad.hex
When I try to configure the retropie Input with a PS3 controller it shows 2 gamepad.
I try to configure any of the Picade Buttons … NOTHING happens.
the external USB keyboard and PS3 controller work fine. But the picade Does not.
So I revert to picade_original.hex. WITHOUT any problems. it flashes correctly.
Now the Picade is detected as a keyboard, I can configure the Retropie.
BUT Select And Start DO NOT work in any emulators. :(

I do not understand what can be wrong?

The Gamepad mode How does it work ?
I mean, I can use Keyboard and PS3 controller. but the Picade does not seems to work correctly.

Any ideas to help me solve this case or should I return the product to the seller ?
My Picade PCB is blue and seems to function fine except it does not work at all as expected.

Any help is welcome

Thanks in advance.
