Old component set wont get off assets page

Hey, I have an issue with a button component set that has been updated.
The first thing that happened was a difference in lowercase and uppercase letters, so the new set didnt replace the old one completely. Now everything is exactly similar, but the old component set wont get off the assets page.

All the old components are deleted and gone, so when i ask it to show main components, i only hit a blank spot on the page where it used to be.

Do i have to manually go into each file where i have this problem, and replace the old ones with the new buttons i have made to get it away from the assets page?

cheers
Sverre
