It was tags from a manual copy-paste from open data of the cityhall that I forgot to remove. 'NOME_AREA=*'is 'name=*' and 'TIPO = PRACA' is leisure=park. Now fixed. Thanks for letting me know.
As to the difference between source and source:name:
'source' is the general tag to cite the source applied to all aspects of the feature, both the geometry and the tags.
'source:name' is the tag to cite the source of the name *only*.
I use both tags to say that the source of an object is from a certain entity or doc except the name, which is from elsewhere.
