Popup dialog interactions background dismiss

I’m having trouble with the popup dialog I made. If you click on one of the courses made, it will open a popup fine. If you click the “X” in the top right it will work fine. However, if you click on the background-- only the overlay will fade and dialog will not actually dismiss.

Any idea why? Thanks!
