Scaling Down In SolidWorks

I'm relatively new to solidworks and I've been set the task of modelling a rear wing for a racecar. Finished it and thought all was good. I need to scale it down to 1/12 of its size for 3D printing but whenever I do this parts disappear. I tried scaling down to 1/8 and that worked fine. This is really bizarre but I can't work out what i need to do. I've attached two photos to show what i mean. I've been searching to see if anyone else has this issue but can't seem to find it anywhere. If anyone can help me out it would be really appreciated. Thank you.

EDIT: I've attached another photo at 0.1 scale. Here only some parts disappear.
