Hi again,
I want to apologize. I think I was a bit too quick on the revert button on this one when the only detail that was wrong was the wikidata link.  I've updated the details mostly back to what you set while also adding a bit. I've also added "Utilita Arena Cardiff" as a alternate name to the wikidata object. i'm not sure the wikidata procedures but that the main name of the object possibly should be updated too but i'm unsure on that one.

Kind regards,
Kits
