player 2 maps buttons normally but 2 of them do not work in MAME

Hi guys, i have this strange problem on the bartop I'm setting up, the buttons on player 1 and 2 are mapped correctly, but when playing MAME games, for example street fighter II, the buttons equivalent to player 2's medium kick and strong kick do not work.

This happens with other games, like street fighter alpha, but not with mortal kombat 3 for example.
I checked the mapping of the buttons on the retroarch using select + B, and they are correct, but in the MAME settings the buttons on player 1 and 2 have no reference and it is not possible to change them.
What could be happening? Has anyone ever experienced this?

NOTE: some information

Batocera 5.25 PC
Romset: MAME 2010
Controllers: DragonRise USB

Thanks for listening!

Yeah well it is apparently a known bug with MAME 2010, 2 buttons for player 2 does not register no matter what you do. I have read somewhere that some guys found a work around, I am totally new to this thing and let me tell you it is pretty much rocket science for me. I will try to find the post I think it was on reddit. Still trying to figure out how to enable the sound for batocera…

Jagd what is your problem with sound? what is the hardware that you are using?
