vacation accrual "current remaining" does not match totals

Have two employees that show a current remaining amount of vac pay that does not match the report totals of accrued minus paid.

Have tried entering adjustments in transaction history but it always adjusts both the current amount and the report totals. 

What am I missing? Both employees have had multiple terms of employment as they are seasonal so I suspect this may have something to do with it.

Vac pay is not set-up with a carry-over amount
