Shape fill effects - Changing multiple at once

[leavuc]

Hey people, I have a question.

I have a frame by frame layer, with multiple shapes in each frame. I dont excatly know how it happened, but when I was drawing, some shapes ended up having the crayon effect applied on the fill.
Is there a way to reset this effects fo all the shapes at once back to plain?
If I select all the shapes, the fill effect panel becomes grayed out (assuming because the shapes have different effects)

Thank you for your help!
