Stroke not working after creating shapes

Hey,

So, thanks to After Effects not being so good with variable type. I'm trying to import my logo into AE which I then go to 'create shapes from vector layer' While AE does this, It seems I can't add a stroke to the shapes. instead there is a question mark (see screenshot) in the stroke window. No matter now many times I try to change this, It wan't let me apply a stroke. Any ideas?
