Are you playing on mobile? Are you playing coin games? Those are are practice rounds and not Ranked Rounds.
If you are playing on mobile touch the 3 stacked _ marks to the left o f the WGT Logo on the top left. Then touch courses. Pick a course like Pebble Beach. Select F9, B9 for F18 and touch.
A window opens that says Ranked or Practice. Ranked is the default If you touch Tee Off the round will start. Ranked rounds has everything locked for your tier. Practice allows you to set all of the settings: Tees, Hole Locations, Green Speed and Wind.
As you play ranked rounds your average will change.
Hope this helps. Good Luck,
