1. It is incorrect because in Poland, the Tatra Mountains have TOPR, while the rest of the mountains have GOPR
2. In Poland, "GOPR" (Górskie Ochotnicze Pogodowie Ratunkowe) is a proper noun, but this looks completely wrong and confusing outside Poland, and Czechia because mountain rescue services are called something else in those countries. For example, in Iceland, they are called "Slysavarnafélagið Landsbjörg."
3. Category names should be as short and unambiguous as possible; they should not include explanations, like the Polish one I’m referring to.

The category name should be 'pogotowie górskie' (mountain rescue). Written in lowercase letters, such as all the rest categories.

This can be better understood in the context of fire departments:
'straż pożarna' (fire department) – the correct name for this category on mapy.com
'Państwowa Straż Pożarna' (also PSP) (State Fire Service) – a proper noun, valid only in Poland. But in Poland there is also the 'Ochotnicza Straż Pożarna' (OSP) (Volunteer Fire Service).

It is clear that proper nouns are not suitable for category names.

I reported this bug once using the bug-reporting applet, back when the forum didn't exist yet, but the bug still hasn't been fixed.
