There was an incorrect file in the original release of BLS2015 that caused the Worksheets to be calculated incorrectly. In order to fix this you need to do the following in the order list.
1) Down load and install the latest BLS2015 update.
2) Open the program and then open Certify/System Default Fees. Verify the USBC settings for Local & State Merged/Not Merged and the Local and State Fees. Close the screen and save any changes.
3) Open your league and open Certify/Association/League Association Fees. Click on the button on the top that says "Reset To Default." Once it finishes resetting the fees, verify one that the USBC settings and Fees are still correct. Save any changes and close this screen.
4) Open Certify/Bowler/Bowler Management and go to the "Certification Worksheets" tab. Click on the button "Recalculate Worksheets." This will fix the errors and the numbers should appear correctly.
Repeat steps 3 & 4 for any other leagues you have that may be experiencing this problem.
