Cannot make topic in "Game Discussion"

I wanted to make a topic in “Game Discussion” to bring attention to a fairly major bug with the newest update, but noticed that the button was greyed out, and when I hover over it, it states “You’re not allowed to create topics in this category”.

Is there any specific reason why? I do not remember receiving any warning about this.

Edit: Issue resolved, seems that unlike sections like “Machinery of War”, I need to select a specific category.
