when i ctrl click warbound items, it will not always put all the warbound items from the bag into the mailbox

i am using bagnator with postal

The Express feature uses the Control-Click to attach similar items to a mail.  Similar items are determined by item type as defined by Blizzard.  Warbound is simply a new state of if the item is soulbound and if so how.  In this case bound to characters on the same account.  So Warbound is not a matching definition for items.  So, this is working as intended.
