Pin Map Strange Behaviour

I have 2 sheets, People and Areas with Relation columns built for Area

I have a Tab set to display the Areas which is fine. When I click on one the areas, the Pin Map displays correctly BUT if I go back the the Areas screen and this time select an any Area other than the one I previously selected, I get a details screen instead of a Pin Map

If I reload the app and select a different Area to the one I originally selected, the Pin Map displays correctly. This happens to all 10 Areas; only the first one selected each time displays its Pin Map

As I am still evaluating Glide, I am using the Free Version which, of course, limits a Pin Map to 10 Pins

Any thoughts?

Thanks

Kevin

Do you have a video of this happening?
