If you directly go to tavern & hire units , it is not marked as complete.
You have to go to quest window, than click the task & than set sail (It will lead you to training window) now hire the amount mentioned in quest & once those units get trained, quest will be fulfilled.
Keep in mind if you have already units in training & new marudar's are at the end of list than quest will be completed when those (which were at the end) get trained.
