I just tried to do it, it won't let me. I believe it's because of the coding you used, so I can only use Source Editor and Source Editor doesn't allow you to delete categories for some reason. I see two options:

1. Copy the coding, then delete it. After that use classic editor and delete the categories, then add the coding back on again.

2. Leave the categories.
