Hi,
If you create a products listing of all the products under the main category and that under that category you have an unpublished category, the products under that unpublished category will still be taken into account and displayed.
You really need to put that unpublished category outside of your main tree of categories so that the products below it won't be taken into account on the products listings.
That's probably what is happening here.
Regarding the google feed, it indeed takes into account all the products, even the option ones. We'll fix that for next version of HikaShop which is to be released this month.
