Ok, Im on their position (exact co-ord) and I cant add them to my party, My party is not full and they are mine (assigned as manager and supervisor)

And ideas how I can get them from the ground into my ship? (an AA-9)

Sounds like a bug. IF you are at the same coordinates and IF they have been assigned to you they should be put into your party and go with you onto your ship. So it sounds like you're doing all the necessary steps. Report it to the bugbase.
