Zsphere help, preview mesh problems

I am new to Zbrush and just started to work with Zspheres, so far any time I try to see the preview by hitting A my mesh just shoots of in to infinity

If I start with this simple Zsphere setup I get this

This only happens when I am using symmetry and I have used Init Zbrush 3 times with no change. I have no idea how to fix this and any help would be appreciated
Thank you.
