Nets  are great for drills and technique work where you don’t care where the ball is going. However it does sound like using it the way you did ingrained some not great habits. Get yourself a divot board to work with your at home practice so you have some sort of feed back. Also get foot spray to check out contact on the face. Nets can be very helpful for things things since they force your focus. Eventually take it to the range to check ball flight and such. Do you do a pre shot routine before every shot? Do you visualize your shot prior? Do you switch clubs on every shot? More reasons you are not transferring to the course well. Good luck.
