Why isnt the mod named in steam?

In-Game Company of Heroes, why isnt saying In-Game Company of Heroes Blitzkrieg Mod? I've seen it properly named for some players but for most is vanilla coh.

Edit. Found out why. It's named Company of Heroes Blitzkrieg Mod when just the launcher is opened, when the game is opened it changes to just Company of Heroes. It would be great if something could be done to see it named properly.
