Push Button for the Heads Up Display Not Working

Please let me know why and what I can do about the push buttons not working properly. The reset button does not work at all. One example is the oil change reset button, setting the clock and date, compass. The check status button to the right and left of the push button parts seem to be working and odometer, distance to empty button seem to work... What are my options to fix these problems. I thought about unplugging it (just for now) so I do ot have to look at the change oil head up display, but that is not the root cause and not sure if this will effect anything?

Thanks in advance for your help
