HA05 Problems Updating Neighbors

I have several Ha05 controlling outdoor lighting on the front of my house. One device has four neighbors, one has 5 neighbors and the other has 8. I just added two Ge outdoor lighting controls 5 feet from the device that has 4 neighbors and the device that has 5 neighbors. They are not seeing the new devices. I have performed a Heal and update neighbor nodes on each device.

If a device is not showing up as a neighbor can it still recieve the z-wave network signal from another device?

any suggestions?
