I struggled with this. What I've learnt: In my case at least the invalid job needs to be started first time, in a session, out in the open. I.E. on the Cayo Heist I have to exit the sub. launch the invalid job, enter the sub, launch it again. Then it works. While doing the preps if ever the job icons do not show whilst inside the sub repeat the above. When I was first trying it, launching only within the sub, the job icons did not show so I launched from the 'Play Job' menu. But that did not work. It teleported me to a mountain.
