Thank you, now I could log in 🙂
The reason they don’t appear unchecked is because you have manually selected some, and the checkbox states in the selection override that: https://i.imgur.com/n78tzD7.png
If you uncheck that, it will resolve that.
The missing results are due to the other two options: https://i.imgur.com/MPchceC.png
Those are actually post categories, and are not defined for the post type you are searching (articulos). So selecting either of them will yield no results, as nothing matches either of them.
