Symptom

Newly created maps cannot be added to new map locations. When trying to drag a map to the right column in the map selector field, it only scrolls to the top of the page and the map is not added. 

The issue is encountered only with maps and locations added from a specific date onwards. Adding and removing maps with previously added maps and locations can be done with ease.
