This recently happened to me while playing co op on the first crystal wraiths act with three other players. One them had it bug out the same way too. My lore trophy for the main game popped just fine though. Haven't done the expansion maps yet though.

Same here. I completed all collectibles (reliefs, paintings, tomes and tablets) and read each one but the exclamation icon still shows on my journal. Not sure if this is why I still can't unlock the "Now it makes sense" achievement. Please fix.

I have the same problem, and not just at Journal Entries, also at Feats. I hope they will solve this soon.

I have Viewed trophies and checked all the Journal Entries for my Wulfgar Character and the Exclamation Mark does not disappear as well, this just happened today after my Last Session with Wulfgar for Level 4 Act 1 of Companions Of Icewind Dale.

Viewing trophies worked on 3 of my 4 characters. My first character (Cattie-brie, day 1 character) still has notifications on her trophies (and feats) that won't go away by any method I could try, including viewing the trophy nook.

Go to the corner of the hub where your trophies are click to view those that should get rid of the check mark.
