1. I have created a list of metafields on brand/product type level
2. I have created templates per product type
3. I open the customize theme
4. I go on template level
5. I start assigning metafields per product
6. I realize that no matter what i do, the metafield for all products in the same template gets assigned to the metafield of the last product i edited.
