Hi Dear,
I have a problem with one product (say, product A).
Product A has children, and is orderable.
When I go to custom fields in product A, and select option "Disable inheriting" (so that children don't have the same config for custom fields), the same custom field disappear.
This happen (at this moment) only with that product A. I've created other product in the very same manner, and doesn't have this problem. The only difference is number of children (max 9 in other product for which options work well; 13 for product A).
Any suggestion about that?
