Hi guys, for some reason I cant seem to get my models tab open. When I press M on my keyboard my models tab does not open. Right clicking and pressing models just spawns a red box (misc_model) and nothing else really happens. No seperate window comes up like when spawning prefabs

I've searched around on the internet and I couldn't really find anything on this issue I'm having. If anyone could help out that'd be cool, thanks<3
