CLONE 2020R1 - 2020.R2(S3): TBC Reversal is not adjusting the customer balance correctly

Assigning a new customer to an existing TBC, when I check the customer balance, the adjustment to is not correctly reversing the amount owed.

ex.
Customer 1 TBC $5.00
Assign to Customer 2 who has a credit of $20, so Customer 2's balance is now $15.00
Reverse back to customer 1, the balance is -$25.00 instead of $20.00, the balance is correct in tbCustomerOnAccountBalanceEvent, but not in the customerInformation table.
