Fix - Change of Plans not applying credits properly in Main-Sub Accounts

Currently, if you apply a Change of Plan in a Sub Account, the Splynx software creates the credit note and then creates the new invoice into the Main Account. When it does, for some reason, the credit note is not applied to the corresponding invoice and sits on the account as “refund due”. Unless you catch it at the time and you are able to delete it, there is no way to apply the credit to the related invoice.

If possible, could this be fixed?
