This typically happens when there is a mismatch between the charge fee date and the finance processing week.
To investigate, start by going to:
Finance module->Charge Fees
Search or locate the Charge Fee. This screen will by default only shows Active charge fees meaning they have not been processed yet, so you should be able to find your charge fee transaction in the list.
When you find the Charge Fee, check the "Date". In order to be included in the Finance run that date needs to be within the Finance week period.
You can check the Finance week period by going to Finance module and locate the Weekly Processing section, it has the inclusive start and end dates there
