Flight time calculation error!

Hey guys, I am returning to Mission Planner but have an issue I cant figure out. The acreage shows correctly, but this is no where near a 47 mile map mission. It shows and 11 hour flight time. I have flown this using other planners and know for a fact this should only take about 14 minutes. What is going on here? Grid flight is set to go 7 MPH. Is there a setting somewhere I can change?

Your home position is somewhere 47 miles distance and flight distance and time calculated from Home.
Set home before start survey planning.

Okay, may I ask another question, I figured out how to move the home point and that was the trick. where are the settings for home point altitude?

Home point altitude is set from the google elevation map, usually other waypoints are relative to that, unless you set it for absolute or terrain.
