I exported a category with the sub-categories. Many of the products are grouped products. When I exported this time, the entire column of "ParentGroupID" is all "0" even though some are simple products and some are grouped products.
Just to add, the last time I exported, the parent group ID's were shown by a number. Example: 2166
Im not sure what I changed when I exported this time, but it must have been something?
Thanks People!
