Gallery will not be added in the table

When I try to add some gallery pics, they will no brought into product table.

My working steps:
1. Open Bulky with button at woocommerce products.
2. Set a filter to a category
3. Select gallery pics after upload to the media gallery. Confirmed the choice of the pics.
4. => nothing from the pics choice is in the table.

I bought the tool, because I could understand that as limit for the free version.
