I want to update an item “shirt” which is a Serialised items.
Item has 3 serial no such as shirt001, shirt002, shirt003.
But when reconciliate item with shirt001, shirt002 as one serial( shirt003) damaged, it showing error

Error: 2 Serial Numbers required for Item . You have provided 3

On checking I found that even I remove serial (shirt003)and save,(shirt001, shirt002, shirt003) all serials again loading from the database cuasing the issue.
