CE:Unable to extrude a complex shape with parametric option activated

Hello,

I created a complex shape and tried extruding it parametrically but was unable to do it. I'm receiving an error saying "An error occurred creating Feature: "Solid of Extrusion #2"

But when I turn off the "Parametric" option in the menu, It can extrude the complex shape.

I am using Microstation CE Update 12
