By that “[CC 1.0]” in the title, did you mean “CC0 1.0”? (i.e. CC Zero v1.0)
“CC” just means “Creative Commons” and they have a bunch of different licenses. (I guessed CC0 because that’s the only one I can think of which is still at version 1.0.)
If so, would you mind setting the “Asset license” field in the More Information box to make that clear?
