Help with unknown lines polys in 3DS?

rkell48

Hello there again,
3DS Max NOOB here again

I was modelling my character when I noticed a strange set of poly's/edges

What are these and how do I get rid of them?

You've obviously chamfered those edges by mistake at some point.
Select the 2 side edges of those "rectangles", collapse, then suppr the extra points.
