How do I use these normal textures that shipped in my shelf?

Joltya

Hey everyone. When I installed my copy of Painter (using a studio license), I noticed I have a lot of normal textures in my texture shelf, which as far as I know doesn't normally happen. Am I able to use these to actually make tools and stuff? What are they here for? If they're just useless and there's no point in keeping them, how do I get rid of them?

They are normal stamps for hard surface work and skin grain high quality scans that you can use for any project.
It's a little messy at the moment because everything is in the same folder but the next major update will bring a new shelf and make all this much easier to sort through.
