Searched for "Drury Plaza Hotel St. Louis arch".
Address with Pin and Map is shown.

At the bottom of the page, i click on the layer and select Satellite

Pin has now been removed from location.

I tried this same test with many of the other layers and it is repeated each time.
If I switch the base layer, I would expect the pin to be redrawn with the new layer. This makes it way easier to find the location I was looking for. If not, I will have to back to the main search and start over with the new page.
