Ha! Gotcha! You've shot yourself in the foot with that note!
Firstly, I strongly suspect that you know your way around OpenStreetMap. No normal user would know that this rule exists. Next time, don't make an anonymous note but correct it yourself, logged in with your user account. Now to the actual problem: The shooting club is the only user and owner of the building, there are no other "POIs" in it. Therefore, your rule does not apply. On the other hand, it does not apply because the name is clearly written on the facade outside and therefore this building can very well be named as such! Everything remains as it is!
