Pricing structure can't be seen all of it in the control panel
Another bug I've found on 3.0.4 is that when your categories/subcategories have large names, than in control panel -- Pricing Options, the categories/subcategories can't be seen and you can't insert the price for all the categories because you can't see them and their inser box.
I am talking about the categories/subcategories that are on the right side.
