Although by now I'm sure you have done more research and figured out the problem. If not, I may walk back that statement, depending on what apex you have, you may not have a display, but if you have a display tap the middle button:
select "Control/status"
select "Manual control"
then scroll down until you find what you labeled that MP10
Select the MP10 and the On Off Auto will hihlight.
Turn it off.... Verify
Turn it on.... Verify
If all works well, put it back on auto.
