Odd green high light on some cells.
I was trying to grab some cells in a group. I held down FN, Control, Or Option trying to do this. When I did it turned some cells light green. I have checked conditional high lighting. Noting is set. It is like a ghost setting of some sort. I can't get it to turn off. If I delete a column or row, when I bring it back it is green again. See picture. Please help.
