CLONE 2020R2 - Customer Sales - Customer with Credit Balance not being used

Scenario - 00663 in testing
April 15, 2020
Create a Credit Balance on - Cherokee Creek Boys School, In for $6
Enter a TBC on the POS for $3 and assign it to Cherokee Creek Boys School, In

Defect the invoice is displayed on customer sales but the remaining credit is not displayed.

As it does with other customers that have credit balances

Example :

NOTE- when this scenario is in place - same day credit, it seems the page has other one off issues. for example - if you navigate away from Customer Sales, then back - no data is displayed. I am not writing a defect because I think this is caused by the primary defect above.
