If the points appear to be doubling for a week, please check the following:
Go to Setup > Lane Assignments and make sure the week is not designated as a 2X Points league.
If that is not the problem, make sure you have updated BLS-2015 to version 27.03.11 or newer which resolved the problem.
If the problem still exists, go to Setup > Rules > Team Points and set the team scratch points for game and series to a different value. Close the rules and reopen the rules and set these values back to zero.
