I have same issue so I post here
Let’s say I have a product with 3 variations
ID 0001 – Brand-1 | Including Box
ID 0002 – Brand-2 | Any Attribute Options
ID 0003 – Brand 1 | Any Attribute Options

The problem is, in front end if I select the first attribute (Brand 2) then second dropdown box (Package) still have the option to select “Include Box”, but there is not product with such configuration.

This does not have logic, even if I add a new option to “Package” attribute like “No Package” when I choose Brand 2 will still show both Options.
I need to hide the second dropdown box and allow Woocommerce to add product in the cart if there is not any option set for “Package” attribute.
Thanks a lot.
