Hello, good afternoon, I have this problem in the photo, the name of the last 3 classes does not appear, and consequently every item that has a bonus for these classes is left without a description.
Right click on the game in your library, go down to Properties and over to DLC. If they are ticked you can either try verifying them - Properties again and then in Installed Files choose the verify option - or you could untick and then tick the boxes again which may trigger Steam to download them again.
