Custom Content Badge marked incorrect in gallery

Hi there,

I have just spent days building this house to see the gallery say it uses custom content which it doesn't. I then moved it to a new save file which didn't work. I tried removing my mods folder so that my game has no cc or mods whatsoever that also didn't work. Lastly I tried turning off cc in settings resetting the game moving the build to an entirely new save file and re-uploading and yet the badge is still there?? I don't know what else to try just wanted to post it without the badge.  

Any advice?
