The report you show is ticket payments. Those tickets were paid by the account so for payments report it is correct and it have mooved from sales/receivables to account the same as it does for cash or card.
For customer accounts what you are presumably looking for is something to report accounts and their balances.
Have a look at this and see if it helps at all;
Note that when the accounts are paid the payment is not a ticket payment so doesnt report in the ticket payments expression hence the report in the linked topic.
If using accounts I would also look to create a section on the report to show the account balances so you are able to monitor the balances and stop anything getting out of hand for which the simplest solution is a accounts balance section on the work period report so you see it every day.
