Enter address to check lattitude and longtitude

In the back end, I can't get this option to work. When I enter an address, I do get a red marker, but nothing else. From a google search, it looks like I should be able to right click on the red marker and choose what's near which brings up a green arrow. Hovering over that is supposed to give me the lat and long, but I can't get that green arrow. Right clicking or hovering over the red arrow doesn't do anything.

Any suggestions? Such a great feature!

Hi,
I don't understand what you mean, please attach the screenshot to make your question clearer.
