I'm trying to discover what is going on with mapframe maps on this article: Lista de governadores das unidades federativas do Brasil (2015–2019). It's blank, no matter what I try to do to solve. The query is correct, it returns the right amount of items (27 states). Some time ago one person changed the P31 of all states of Brasil on Wikidata, but it was reverted to the original P31, I'm not sure if has influence or not. Can anyone give me some light on that? Thanks!
