I am new to Vue and I have run into a problem that I can't resolve. When I create terrain and enter the "terrain editor" I notice what appears to be two terrains over top of each other and I can't work with them. I've attached a screen shot to illustrate what I see every time. I also noticed that I'm unable to use the "reset" option. Most of the time it's grayed out and when it is active and I select it, nothing happens to the terrain!

If somebody could please offer a suggestion as to what is happening here I would appreciate hearing from you.
