Issues with Cloud dunning (Collections)

I have the following two general situations:

1) On the customer site, there are invoices in different currencies – the calculated dunning letter total seems as if it converts currencies to DKK before adding it up.

• They must have divided the dunning letters in relation to currency
• The sum must be in the relevant currency - they cannot send dunning letters to foreign customers with sums in DKK

2) If there are invoices on the customer site that partially entitle a dunning letter1 and a dunning letter2, two dunning letters are created - but the total on both dunning letters is the total sum of all invoices
