Ok,when ever i delete a pack of items of so say like spacebuild items and like a motorcycle this happens.

After i delete it it STILL shows the spawn category and icons it was under.

SO for spacebuild like it would show.

Space-build-Ramps and then inside it it will show the props but i deleted that?

SO can anyone tell me how to let me delete the categorys i origionaly deleted?

Delete everything in the folder. Gmod will re-create the needed ones when you launch it.
