cccam newcamd confused!

I have a cccam file from my supplier. It contains a line beginning with N and it shows up as using newcamd. Confused?
I've added a 2nd c line to the cccam file and this shows as using cccam-s2s.
Problem is, I want the 1st line (N) to have priority over the 2nd (c) line, but as soon as I add this second line, this becomes the default line. Any ideas?
