Some of questions.

What desktop are you using?  The NetworkManager GUI displays are a bit different
between KDE and GNOME.

Are you using the GUI to configure the interfaces or doing it manually?

I think the problem is that in your config file you have both

and

I don't use DHCP for IPv6 in my network since Android devices can't use it.   
So, I
manually configure IPv6 for systems where I want a "short" IPv6 address and 
they are
"servers".  For the other systems I just let them use the IPv6 native 
auto-discovery
do its things.

I believe with both of those parameters defined the IPV6_AUTOCONF takes 
precedence
and will prevent the dhcp-client from starting.

FWIW, using the GUI on KDE I could not force my config files to have both of 
those
defined with "yes".

there so
many of them?
