try some simple fault finding,
unplug the connections to each switch that shouldnt be on one at a time, if they stay on or/and the other two drop out as well theres a short, re plug each afterwards (all this can be done with it on, its low voltage) , if that fails unplug the lot (of problem ones) so no switches can mechanically be made and connect one at a time, checking as you go, another thing whats your set up? are you using those letters/key inputs for something else? a pic of your button wiring might help a bit more, depending on your setup if you have enough spare inputs you can always map your spares to what you need if there is a fault with the card
