We recently took on a new property in our property management section. Most tenants had balances from the previous management company. These balances were added as OPB journal entries. 

When running customer statements, the OPB is correctly reflected, as well as in follow-up reports. 

When we receive a payment though, the opening balance journal entry does not show in the different screens to apply a payment to. 

Secondly, tenant had a credit as the opening balance, how is this adjusted and applied to the new invoice raised? 

Looking for some practical help on addressing this.
