Comment 7 for bug 1810429

After some further discussion, I think this needs some discussion from the wider community - the refunds UI is overall fairly confusing. The Refund action itself doesn't do anything unless a negative bill is selected(possibly greying out this action when a positive bill or no bill is selected would be a good course of action?), and even then is only effectively a placebo(it brings up a modal saying what it's doing, but that's already done when you select a negative balance). It seems to me that the refund button might at this point be worth removing entirely.

The buttons I introduced might be confusing, as well. On the surface, it seems sensible, but issues arise with that mix of refundable and non-refundable transactions. A third button, "Refund & Apply Payment" might help with this, only displaying when a mix of refundable and non-refundable transactions are selected. It should also be noted though, that these buttons are functionally identical, so it's more a wording-change than anything.
