We have an issue with appleid amount which somehow is double to the doctotal of the credit notes copied from an open invoice.
invoice doctotal is 10
Credit note doctotal is 10
applied amount is 20 ?
OPEN BALANCE become 10
The customer ageing is OK but the credit notes is 'open' and for the dunning procedure shows the open credit notes (as positive open balance) and the total due is wrong.
It is not possible to figure out why it happens because it does not happen for all credit notes.
