Hi,
I have been playing today a few missions from the reforged version campaign (in normal difficulty). I have just checked and I’m only getting marked as complete a few missions, while I’m at the 8th one.
You can easily check it in the following screenshots:

I’ve done multiple different playing sessions, playing one or two missions each time, and only got disconnected once, just a few minutes ago (I guess due to the maintenance, as I have a warning and was logged out).
Not that I really care much about unlocking some portaits as long as I can keep playing the campaign missions, but still is a bug (and disencourages me to even attempt to play again in hard mode).
Sadly I don’t keep all the savegames of the human campaign (I always delete all but one save).
