I think I have an explanation – I had an impression that all of the articles have slugs that much their titles (e.g. Estafas comunes de inmigración que debe reconocer -> /estafas-comunes-de-inmigracion-que-debe-reconocer) but it turns out that this statement is not always true: look at the articles listed above – none of them have slugs matching titles (https://content.saberespoder.com/articulos/finanzas/pasos-para-solicitar-un-itin != Pasos para obtener un Número de Identificación Personal del Contribuyente title from database).

Luckily, I have saved old slugs on Contentful so for these exceptional cases it will be possible to generate pages based on legacy URLs.
