Steps to reproduce:

1. Create new map under Monitoring -> Maps
2. Add element of type Host group and Show parameter set to Host group, Apply changes
3. Add another element of type Host group and Show parameter set to Host group elements, apply changes

Result:
Two things occur:

1. The second created element with show type Host group elements is automatically moved to the center of the screen and there is a blue overlay over the rest of the configurator;
2. If you attempt to click the other Host group type element, it does not open the configuration overlay for this element
   

Expected:
You should be able to click on any other element in the map and open/edit their configuration form
