We have been bringing points directly into a 2012 Civil 3d drawing using the same method for quite a while. We use a numeric descriptor code and the points are filtered correctly. In this particular drawing, one description code was singled out and "locked" in the drawing. The points and symbol show in the drawing slightly muted but when I try to edit the points I am unable to do so. I have tried the "unlock" command with no result. The symbol displayed by the point number is a red circle over a pencil.

Credit where credit is due! Give kudos or accept as solution whenever you can.
I had the same thing happen and I found that my layers were frozen and locked. Just Thaw and unlock layers and you have access to your points.
