The progress of the Terran campaign is not reset. Initially completed all campaigns on “Beginner” difficulty, the status was displayed correctly. Later I decided to replay the Fighter on difficulty “and the status of the Zerg and Protoss campaign was updated, but the Terrans do not. Here is a screenshot that the Terran campaign is not considered completed on the” Fighter ": imgur#com/a/6LwZlRw (replace # on .)
And here is a screenshot that I passed it on the “Fighter”: imgur#com/a/g4tHZr9 (replace # on .)
Maybe I need to somehow reset the campaign progress?
Go to your achievements page. There is one for completing every mission in Wing of Liberty. There is a detail on that achievement. It will tell you everything you need to know.
