[Koha] check out one item results in multiple of those items

We have started experiencing a recent issue where attempting to check out one item results in multiple of those items (same barcode, checked out multiple times) being checked out to the one patron. This does not happen to every item, nor does it happen to every patron. </file/t341338/error.jpg> -- Sent from: http://koha.1045719.n5.nabble.com/Koha-general-f3047918.html
