We made two things much simpler in ZeeMaps:
1. Reposition makers by just dragging and dropping them to the new location. Make sure you don’t have grouped markers. You can temporarily turn off marker grouping by un-checking the menu item “Settings -> Markers -> Group markers close to each other”.
2. Double-click on a maker to make changes to the marker’s details.
Both these are available only when you have Admin access to the map. If your map is locked (Map Access on the right top of the map says None), use the Map Access link to unlock the map with the Admin key. In case you’ve already unlocked, but it still doesn’t work, try refreshing the map page as sometimes the session may have expired.
