These have been missing since start of season on NA.
You can simply go to another X7 POI(even ones you have already finished) and complete for all of these missions. They reset pretty fast; even 5 minutes or less after you leave and you just have to warp to the required sector to complete that portion of mission then go back to whichever X7 POI you wish.
I reported this early season(here) but looks like they never got added?
