MXC - Collected Sales - full amount of collection displays when partial amount goes to credit

Scenario - Customer #1 Invoice , Customer #2 Invoice, Collected Sale > sum of Customer #1 and Customer #2 Invoices

Collection $100
Apply $50 to Customer #1 ($25 remaining balance)
Apply $50 to Customer #2 ($25 remaining balance)
Click the Credit Balance button - assigning $50 as Credit to Customer #2
Undo Collection from Customer #1

Expected - Collection of $25 should be displayed in the Unapplied Collected Sales view
Defect - Collection of $50 displays - ie full credit amount

Note- at this point this can be done over and over again with the same $50.

Attaching video shortly.
