Thanks Shagrat, It would appear I had something set wrong in the options where it says " Use this setting in all missions. I had mine set to simulation but the labels option wasn't checked. Then I opened the mission again and reset it there also, saved and now it seems all good. Not sure how it ended up that way to begin with considering my other missions worked, may be an update I didn't notice or something.
Cheers, Aussie Pilot.
