Mercenaries Bug Haddgar 14/18 mission

the game just does not recognize the progress on either health or attack on the bar. Used haddgar’s habilities or another char it doesnt matter. the mission is stuck and wont go further cant complete it. someone help please?

Were it those tasks (do you mean numbers 8 and 14, actually? See also below) that, due to bugs, required using Khadgar’s unupgraded abilities in order for the progress to be accounted for and credited?
