Can't delete textures in drop down menu in brush settings

[camiloanaya]

Here's my issue: 

I was in the brush settings panel and I wanted to add a texture to a custom brush. At first I clicked on the plus sign with the square around it (to the left of "Invert" checkbox) and it added 3 additional "Amoeba" textures which I can't delete. (see pic 2)

I tried to restore everything but PS kept adding "trees, water, grass" folders at the bottom. When I right click all these texture settings I added I can not delete them. 

Does anyone know how to delete these items from the texture drop down menu? Please help!

Have you tried deleting via the Patterns Panel?

Ahhh that would've solved it! I re-installed PS. Now I know...

So now that I re-installed PS, the texture drop down menu now only has those three folders in there (trees, water, grass). Where can I add all the other texutres? The paper, rocks, canvas, etc.

Ahhh nevermind -- same place, "patterns panel"
