Ever since I upgraded to 2.0.6 and I make a change to or create a new product I am unable to disable the Override function (1 in image). even if I remove the check from the box and click on save, it reappears. So in effect, all my products are currently "free"
The same applies to the tax and discount type. When I remove the default and generic rules and save, they reappear and no changes are made.
