How Edge fillet was unable to work on the multi section curve but was working on the same circular pattern of that multi section part?

I have attached the screenshot of error coming out. So here scene is that I was making blades of a turbine and I made a blade with multi section and splines and then applied circular crown pattern. Now I want to fillet the edges of all blades as shown but unable to fillet the multi section blade although the other circular patterned duplicates of the multi section is having no such issue tried to hide the sketch, and tried for lower radius of the fillet but no change. Kindly help me here.

Key note: Same fins circular patterned, applies edge fillet all fillets are applied, except of the original fin whose circular pattern is applied showing error that no edge selected.
