I have this same issue. I posted about it on the Bug forums, submitted a bug and a ticket in-game, and have tried several other steps like advancing further in the war campaign or checking other NPCs for the quest. I still have found no fix.
I suggest reporting it as a bug and maybe doing a ticket as well, if this is affecting others it may actually be a bug and not just me being dumb. If you can figure something out otherwise please let me know here!
