Vert snapping on imported mesh

Hi,

Has anyone got any experience of the verts snapping on an imported model. In max there is a distinct space between the lips of my model. But on import the Zbrush the middle verts on both my lips are snapped together and seem welded.

Even when i smooth the tool they stuck together. But if i export and use as a morph in max its all fine. Problem is i cant sculpt them whilst they are like that.

Any ideas?

Thanks in advance.
