Glenn, please try:
1) Redo the map coordinates for whatever image(s) you are testing (Step 2, Map Tab)
2) Add a new image to the gallery and apply the same coordinates and see if it "sticks"
3) Create a new test gallery and add an image and then apply the location
If it fails in all 3 situations, please submit a support request to http://helpdesk.shozam.com and identify the steps you take to create the map location on the Map Tab.
