Serialized Item getting split with 2 quantities in each line

Hi All,

We have a S1 serialized order which has got split after print pick slip(R42520).

Some of the split lines have got quantity 2 and some have got quantity 1 ( Ideally every line should have quantity 1 for the split line)

In the below order, line 29 is split into 29.001-29.020.

The strange part is from 29.001 to 29.008, the quantity on each line is 2 and other remaining lines has quantity 1

We have 2 such orders with different Item number

We would appreciate a quick response on this.

Thanks in advance.

Regards,

Amit
