Madcatz X360 SE - couple of my buttons randomly does not work

i need some troubleshooting help. i got a matcatz sf4 x360 SE fightstick recently. i changed the layout of the buttons (so that default buttons are the far 6 buttons instead of inner 6 near the joystick) and swapped out the joystick for a JLF.

whenever i play on it, my RT and LT buttons sometimes simultaneously just stop working. to make them work again, i just replug in the controller. sometimes, the stick loses connection and automatically reconnects itself to the xbox. i opened the stick up, everything seems wired correctly. one thing i do notice is that the RT and LT button connections are next to each other on the board.

thanks in advance for any help
