On your's the problem is "something" is selected from each group ... and the person should not be buying that way from what I see they pick the way they want it ...

So add to each Option Name Group and --NONE-- and make it Sort Order 0 and set to default ...

Over time ... I may be building in a mask on the Sort Order 0 for those who do not want to see the --NONE-- or nothing selections ...

No promises on that ... I have to see how the Attribute Stock evolves a bit more before changing the logic ... :)
