I have homemade items which are exempt.

In my config setting I have this:

Default Product Type (blank)
Product Type - Top

Google Product Category Default (blank)

Enter a default Google product category from the Google Category Taxonomy or leave blank (note: you can override this default setting by creating a Google Product Category attribute as per the documentation):

1. If I enter Apparel & Accessories, it doubles in my feeds.
2. If left blank - nothing

Findings:

The product type is functioning correctly but the category type is not.

Why?

Has anyone else had this experience or problem?

Thanks
