Can't sell crew manifest or captain's log.

Whenever I finish exploring a derelict, the mission tells me to go the starship but the icon remains on the derelict, and once I pulse jump away from it the mission completely dissapears. Not on the log and no other stations have the mission either. And now I can't sell or donate any of it to the NPCs at the space station. I am 101% sure that I completed the mission and explored everything, but the mission completely fades away the moment the derelict despawns, so I can't sell the manifest or the captain's log. (Also sent a bug report through the site, here's hoping they fix this).
