Hi!
I think you are using Infinity UI++, and the problem is probably related to that.
You could ask about it in their topic, drunktiefling had some HLA screen related problems too, that he could solve somewhat:

If you are coding inclined, you could figure out something from his fork of the mod:

You will probably need the NearInfinity tool to edit the UI.MENU file:
