You've already used the variation value to the other options!

I am trying to set up a product and the product has many variations. It is a device with 4 screws. All 4 screws are the same. When I add option for 'screw one' : 1 2 3 4 mm as follows. Everything is fine. But when I try to add second option 'screw two' with the same data 1 2 3 4 mm as follows it becomes impossible and the upper error appears. Can we make it a warning not an error?
