I have a custom attribute named container that is a select field. When I use Update Attributes to update multiple products at once this container attribute is always enabled even though I haven't checked the Change box underneath it and when I update attributes it actually gets saved. This attribute is for simple products. I've also noticed that when I edit a configurable product it's not disabled there either.
I have another size attribute that works just fine so I'm not sure what the difference is. Anyone have any ideas?
