Hello,

Next time you change two places far apart from each other, it is better to upload them separately (i.e. change the first clinic, upload, and only then move the map to the other location to work on the other one).
This is because your edit generated a large bounding box covering about a third of the Netherlands and Belgium.

Have a nice day.
