For a start, Accounts Payable being a Liability account can’t have your Accrued Expenses (the contra) also as a liability account - it should be an Asset account, expenses are debits and so are assets.
When you say they aren’t appearing in the Accounts Payable are they appearing or not appearing in the Accrued Expenses as well ?.
What dates have you entered for Settings - Start Date and for Summary tab - Set Period.
Both should be Jul 1.

If there is still an issue, post a screenshot of the accounts payable entry.
As an aside - try and use another “regular” account for these one off transactions. If you use Accrued Expenses then you are stuck with this account forever as currently COA’s can’t be marked as inactive. If you have a clearing account used for bank rule bank transfers - then use that.
