Reports, Account Trial Balance Report, "Overdue (adjusted for Maturity)" column did not show prepaid values

The Account Trial Balance Report "Overdue (adjusted for Maturity)" column did not show prepaid values.

If the Account is post maturity, the value printed in the column should be the Account Balance, unless it is a credit/ negative in which case it should be zero.

If the Account is pre maturity, the value printed is the same as the Overdue column, ie the sum of Transactions.Overdue, and can be positive or negative.
