ME3:Can't get the [Liberator] achivement on Steam.

I just completed the mission and the achivement came through on Origin however I did not get it on Steam.

I tried to load to a previous save and complete the mission again but no luck.

I've tried selecting both [Paragon] and [Renegade] dailouge options at the end of the mission too.

I didn't try to replay the mission from the start or on another campaign since those are rather lenghty options, I may try that once I finish the game.

Could someone at EA please check that the steam achivement flags are properly integrated or whatever?
