Relume Cloneable Styleguide

I’m new and just checking out WF so I have a free account but I have cloned in the Relume styleguide. I changed text and changed button colors but I notice when I brought in a component or two that button and button group were not working properly. Can I re-install or bring back in the relume cloneable to start over? Again, I’m on a free account. It says I’ve reached a 2 site limit. Can I delete one and start over?
