I don't know if I'm doing something wrong but this is exactly what I've done...

I downloaded the .json file, the recent one above. Went to Studio > Protean > and imported the mix via file upload then I don't know what happened.

There's a mix called Neat Mix now which looks looks nothing like una.io (has a dark header and looks the same as the normal protean).

When I try to import the file again, it says it already exists.

Thanks
