please think "gross scores" when it comes to the average.
You played 33, 33, 32, 64, 32, 35. Double the 9 hole scores to arrive at scores of 64, 66 and 70.
All these are above your average, thus you can't expect it to drop. Having played about 180 rounds as a TM, it is well saturated (50 best rounds counting) and many a high score has been pushed out ot the calculation. The average will only move to drop until you arrive at Legend.
Thus, yes, it is probably right that those scores didn't move. Play lower scores, 31, 63, to see that.
Have fun!
