[Resuelto] Language switcher still show all 4 languages, even if the translation is deleted

Background of the issue:
I had an Elementor theme builder (archive) template and deleted all 3 translations but not the one in my main language. The Language switcher still shows all 4 languages. Because this is a category menu item, it shows for example in SP enlace oculto which means: Without category.

Symptoms:
The Language switcher still shows all 4 languages, even if the translation is deleted.

Questions:
How do I get rid of the 3 languages for this single page/template?
I only want to see DE (Main language).
