Wind Turbine Animation

I made a copy of the wind turbine and changed nothing aside from the item name but when I place the item, even on Scorched the blade rotation animation doesn’t work. I’ve spawned in the vanilla turbine, placed it side by side with mine and the blades rotate on that one but the copy doesn’t. Anyone have any advice on why this isn’t working and how to fix it?

Upon further investigation it seems that making a copy removes/hides some of the graph functions for some reason so I suspect that’s why the animation doesn’t work on the copy. Why is this and is there a way around it?
