APM 2.8 BAD compass health M8N

When I move the GPS module the compass heading changes with it.

In the status window Iā€™m not sure what to compare? I can See mag_ofs_ x,y,z ?

Ok it is still using the internal compass because the board is now changing the heading in the main screen, so how do I make sure it is using the external GPS. Does the jumper definitely need to b out of the board, and I hav I plugged into the GPS ports next to the front corner of the board
