I am having trouble getting the map marker window to auto-close when another marker is clicked…seems like it just isn’t working since it should be as simple as checking a box in the element editor

I click on one map marker and the marker caption window opens, then when I select a different map marker, I have two marker caption windows open and need to manually click the close for the first marker caption window to close instead of having it automatically close as I would expect it to based on having selected the check box to auto-close.
Anybody else experiencing this?
