Rats nest on all GND connections, despite existing GND plane

split63

I have completely routed a small board manually.  The only "opens", as indicated by the Rats nest lines, are all the GND connections.  I have a negative inner GND plane and each connection has a through-hole via, so why are the GND nets not finding the plane?  Is there some command that must be issued to cause the vias to find the plane?

 Thanks,

 

P.S. Under SETUP -CROSS-SECTION, it lists TOP, GND, Layer 3 and Bottom.   On the Visibility Tab, Under view, it lists Film: Top, Film Layer 2, Film Layer 3, Film bottom.    Not sure if the two should match

     I can certainly change the plane to  positive plane and then use "add shape" to toss in a GND plane, but shouldn't I be able to use negative planes and set the net name of that negative plane?

    At this point I think I will just make it positive and move on.
