vacation entitlement changed with calendar year rollover

Hello.  Quick question.  I have an employee that December 31st had a recorded vacation entitlement of 23.49.  After I rolled over the calendar year end, the program states that his vacation entitlement is 80.07. (no paycheck, no added hours, nothing) I have rolled the program over 3 times, and each time get the same result. There was no added vacation entitlement.  There is no reason I can find for these added hours to accumulate.  I cannot seen to adjust the entitlement hours without messing with the correct vacation paid, vacation earned, vacation released amounts. The employee is quitting, and I need to have the program accurate for March 31st, which is the companies fiscal year end.  Thanks so much for your help.
