Default Major Sub-D glitch!

Hi,

I was well into modeling a character for a short movie and I ran into into this weird bug:

whenever I convert an a poly object into subsurface division (alt+`) it works fine:

Before conversion:

After conversion:

so far so good.

The trouble begins whenever I undo that conversion (using 'z' key), the resulting shape is some sort of mix between poly and sub-d surface:

a closer look:

There seems to be some sort of residual cage underneath, you can see it when I move the vertices. That cage seems to be unselectable as well:

If anyone knows how to fix this, your help is greatly appreciated. I've pretty much stopped all modeling trying to find out how to fix this.

Thanks
