Popup

after playing with OSM some while now i have a (for me) huge problem.
i add several markers to a map and add those markers popups.

my problem is now, that all popups appear at the same time when i click on one marker. but only the attached popup shoudl be shown.

Hi and welcome to OSM and the forum

OSM is just a database and doesn’t support any personal markers or popups.

I assume you are using some kind of 3rd party application based on OSM-Data. Can you tell us where (URL/application) you added these markers?
