Looking at the short video - Concrete ... that can be your answer.
Concrete has usually RE-BAR in it ... steel bars to give strength and rigidity.
Also note Houses have pipes / wires / metal in ...
Any of these can lead to errors.
Even going out to front of house and on pavement / road / drive can be bad ... you have no idea what is under there.
Best place to do calibration is a clear farm field well away from anything.
When you go back to home and desired flying site - the fact it says ... MOVE AIRCRAFT tells you that you have a magnetic anomaly where you are. Sorry but you have choice : Move to safer location and fly or ignore it and have a bad day.
Note - if you get this warning - DO NOT calibrate there !! Switch all off ..... move position and power up again. Still getting warning. Power down, move and power all up again. You may have to try a few places even close to each other before its OK. Why power down ? To reset all so it starts fresh and equates properly the location. I found that when I have this warning that just moving does not cancel it. But switching all off and restarting does.
