Current Handicap is wrong.

Hi, If an administrator reads this can you help.

I amsure my handicap was 24.2.

I entered a scorecard onto my tracker that was shot by a mate who reckoned it had not affected his handicap. I no he was lying so I entered his scorecard on my tracker.  I was off 24.2 and he was off 23.  It reduced my handicap to  21.8 and then I deleted the round.  It has not increased my handicap though back to 24.2.

 Any ideas??
