It's not you but the clubs - there's nothing you might do wrong with them, except for using them.
These clubs are easy to play but you pay with the total lack of precision. Once in a while I use them and I'm sure to have a 3-putt from 4 ft on such rounds!
Change to the Starter clubs in your inventory, this will improve your game!
You might also consider to get two short custom wedges, Ping or up, for further improvement.
Have fun!
