There are One and All buttons that are only shown if you used Features… Planes, and they don’t have anything to do with selection.  If I choose “surface” display style and then click “All” nothing happens because that is only relevant to “solid” display style.  If you click “One” then it changes to “solid” display style, which creates another model with the same number.  Switching to “surface” again would get rid of the solid model.

…. two models are listed in Model Panel with the same number because they are just alternative displays of the same density map.

You can control which style is shown with the “volume” command, e.g. 

volume all style solid
volume all style surface

There is still only one density map, however, so you may just be able to use that model number in commands even though it’s listed twice in the Model Panel when solid style is shown.  You didn’t say what you were trying to do with that model number, however…  or, you could just get rid of it by showing surface style.

In the GUI interface I would open volume viewer and select radio button surface for category Style. Then a little below select All instead of One. I was wondering how to do this with command line?
