Duplicate employer liability in fund accounting

[Gayle]

Our payroll is posted into fund accounting of course, but the problem is that we have employer tax liability as an expense that is posted from payroll and another employer tax liability that is expense that we pay from AP. Were we suppose to set up the payroll employer lialility as a liability and not credited to expense? What did we do wrong? It comes out as a duplicted expense in the income/expense report. How would I solve this problem even from months that are closed?
