In the Create Payment Request → Select Supplier Invoice popup, the same Supplier Invoice Reference is currently displayed multiple times when multiple charges exist against the same invoice.

As seen in the current screen, invoice references such as "VAN12092025" are repeated, even though they represent the same supplier invoice. This creates confusion during supplier selection.

The popup should display each Supplier Invoice Reference only once, regardless of the number of charges linked to it.
