Lasting year to year bug
If you try to export to xls big ISX - you get it with addition column names ( for what ) like this in "image 1.jpg" - see row 42
if position in row before column names is long , ISXD portal breaks it to 2 rows and dubles it SKU, quantity and price
like you can in "image 1.jpg" - see row 41 and 43
You can see it in html output mode - is looks normal like you can in "image 2.jpg"
every time it takes, our partners send us a question and so on.
You can just remove addition page breaking and column name rows. They are not needed absolutely.
