Removing Icons from iOS doesn't work

I added icons to an iPhone project (Hello World) and then removed the icons (in Info.plist, right-click the icon and select "Unset image") - debug via simulator and the icons are still there.

Manually removing the <ItemGroup> section from the .csproj and manually removing the .png files in the project directory works fine.

Looks like unsetting the image in the IDE isn't working? Or am I missing something?

Thanks :) -Andrew
