I've setup bs06 for Flex for 26 pay periods. The first pay period for the deduction is 12/18/2016 to 12/31/2016. When I go through the online enrollment flex is being calculated for 25 pay periods instead of 26. I put the effective date as 12/18/2016 and the first cycle end date is 12/31/2016. Any ideas what I'm doing wrong?
