I wonder if spare parts will affect bosses.

So, I have both Incarnon Miter and Incarnon Dual Toxocyst. When I select the Ready Retaliation for Evo III in Miter, it affects the transformation speed, but when I select it for Dual Toxocyst, it does not. Is this intended? They have the same name and description, but one affects the transformation speed and the other does not.
