I think this has only cropped up in the last Beta or two... but when loading a circular route at the airfield, the system automatically assumes I'm on the last leg and directs me to... where I already am. The only way around this recently has been to insert an intermediate waypoint on the last leg, and delete the final leg back to the airfield. Once airborne, you then re-insert the last leg to the airfield.



It should probably assume that if I haven't already flown any other legs, then perhaps the first one (away from the field) should be selected.



This brings up another issue, choosing which leg you want to fly. If on the PLOG screen you could 'select leg', then I'd be able to go in and override the awkward behavior above.
