Why did adding a row in Numbers create a superimposed duplicate spreadsheet?
I tried to add another row to my spreadsheet. Nothing happened. I pressed the key again and suddenly another spreadsheet with the same figures was superimposed over my spreadsheet. Like when you have double vision. Tried different things as I couldn't read the spreadsheet with the numbers on top of the first sheet. Pressed a key to delete a sheet, and lost the entire spreadsheet.
Why did it suddenly have two copies on top of each sheet that obscured the number?
