Hi Knux900, welcome to OSM. 

Notes like this one are intended to help improve the map so if you see something that's missing or wrong you should use a note, if you can't edit it yourself. You've put this note on a health centre and I don't think health centres are usually pokestops or gyms.

If you want to help improve the map (by adding real life fetaures) have a look at https://blog.openstreetmap.org/2016/12/30/tips-pokemon-go/ and https://www.reddit.com/r/TheSilphRoad/comments/7jqvvl/openstreetmap_what_it_is_and_how_to_contribute/ for some tips.

All the "This should be a pokestop or gym in pokemon go" notes you've added should probably be closed (resolved) by you when you get the chance. :)
