Spawn menu issue

I installed a bunch of addons and recently had a clean install of Gmod, and wiped all my addon folder clean. How can I get rid of the folders (which only contain error symbols now) in my spawn menu? I realize this is most likely a noob question and can probably be solved by the simple click of a button.

Thanks in advance!

use windows search to search for files called “spawnlist” or “spawnicon” and delete any folders by that name in your steamapps directory.
they will regenerate when you next launch gmod… I think

Delete garrysmod/garrysmod/spawnicons

No. Those are icons, not lists.
Delete garrysmod/garrysmod/settings/spawnlists.
