Recently, my QuickBooks file started assigning all manual checks the number "00000000001". This is especially annoying when I am processing payroll. When I assign direct deposit numbers, I would assign "0801201601" to the first record. QuickBooks then knew to assign subsequent numbers "0801201602", "0801201603" etc... I'm sure something was changed in my preferances but I am not sure where to find/fix it.
