Exploiter and Profit taker missions kicking players

[(XBOX)Angel995644]

Upon leaving the elevator to do profit taker or exploiter missions, I am kicked from the squad. I return to fortuna or my orbiter. Once I try to reconnect, the message “objective is already complete” comes up. 
Please advise.

Not exactly sure this is Orb mission exclusive, that happened to me a lot of railjack and a few other things as well, me and 2 buddies go into my railjack, one of them gets kicked, I try and reinvite him and even though it's a fresh mission, nothing has even been killed yet...unable, objective complete.
