I've killed "Naadin the Searing" four times: three times yesterday before the reset when it appeared in my Pathfinder, and once again today when it showed up again. The objective simply won't mark itself complete. Yesterday, I also had the objective to get 40 sidearm kills, which had been complete and uncompleted itself. Something is not working correctly here. Not sure if it's related to the constant Guitar error codes that seem to be correlated with the game losing track of certain information (before kicking me to orbit and erroneously telling me I'm having networking issues).
