If you have never been on a "wide" board, it's pretty common to feel like the board always wants to point high. It just takes some time to get the feel of the board and learn how to turn it off the wind once planing.
Hang a little more weight in the harness for more mast foot pressure, which may help reduce the tendency to point high.
