extra maps indicated on my eTrex 22 ?

When I plug into Garmin Express, it indicates "TopoActive North America 2023.10" as the map on my device. However, I see more in addition to that when I go into the device under Setup>Map>Map Information>Select Map, such as:

Enabled - Worldwide DEM Basemap NR
Enabled - Garmin DEM Map North America 2023.10
Enabled - TopoActive NA, Middle America 2023.10
Enabled - TopoActive NA, Canada/Alaska 2023.10
Disabled - Digital Globe Demo.jnx
Disabled - USGS Quads Grand Canyon National Park.jnx

So what are these? Is there a way to remove? Thanks!

 

I just discovered from SUpport that “Coverage for North America is comprised of three different files on the device. Canada/Alaska, US all states except Alaska, Middle America south of the US border.”
So that leaves :
Enabled - Worldwide DEM Basemap NR
Enabled - Garmin DEM Map North America 2023.10
Disabled - Digital Globe Demo.jnx
Disabled - USGS Quads Grand Canyon National Park.jnx

 

More research shows: "DEM (elevation display) is part of the world base map (gmapbmap.img). It only shows when you zoom way out on the 2D map." So that leaves:

Disabled - Digital Globe Demo.jnx
Disabled - USGS Quads Grand Canyon National Park.jnx

 

Thank you!
