Robot Stops Drive Control Without Being Programmed

[OB1]

For some reason, while we are holding a specific button (button 2 on left drive joystick) the command for driving stops. The odd part about this is we don't have that button programmed in. Additionally we have a command for auto balancing that only works when the button that isn't programmed(button 2) and the programmed button (button 3 on left drive joystick) are held. Any assistance in this would be appreciated. Thank you for the help.
