What you are seeing is very normal. Especially with only 5 devices.
I have over 60 Zigbee devices.
Child Data = 0
Neighbor Table = full, 16 entries.
Route Table = 14 entries. Many of them the same as the Neighbor Table.
So the the other 45 or so devices are not represented in this page anywhere. If I understand correctly, all these remaining devices are children of other devices. A second or third hop away from the hub.
The only way to see the whole table is with an Xbee.
