I want to solve the issue where the height value automatically changes from "Fixed" to "Hug" when combining (click create component set) duplicated components to apply a nested instance.

That issue actually occurs even before applying a nested instance—just grouping the components triggers it. When I manually change the height from "Hug" to "Fixed" after combining the group, the size options defined in the original parent component no longer work as intended.

buttons height is fixed (56)
