In the city street-market dataset, 6 of the 33 have their district field pointing at the generic "Distrito" node, with no real district. El Rastro is one of them: anyone grouping the file by district loses the city's biggest market.

The broken field is address.district, which in these records ends at the generic /Distrito node instead of at a named district. Checked on August 23, 2026; the dataset refreshes daily, so it may heal at source.
El Rastro's neighborhood is on file, so its district follows without difficulty, and this site places it in Centro that way. What does not work is using the file's district field as a grouping key: it loses 6 street markets. It says nothing about the markets themselves, only about the file.
A finding lands here when two documents from the same authority say incompatible things. The contradiction is published with its sources and the date it was checked, and nothing more: conclusions the documents do not give are not written.
