10.0.0.0/8 automatic lookup

I have installed, re-installed the latest dude always get the same problem.

My network consists of three ip schemas:
216...*
192.168..
10.0.0.0

I do not use all of the 10 network. My layout here is as follows.
10.0.0.0/24 main backhaul net work.
hereafter we are routed into microcells
10.0.1.0/24
10.0.2.0/24
and so on and so on. My net work is now in 12 microcells

Even though I started with a clean slate and I intentionally did not ask for the 10.0.0.0/8 network to be discovered at the original start up, DUDE still started discovering it.
