[ntp:questions] server in ntp.conf, but symetric active packets

I believe my issue could be the same as:
Esentially, I have ntpd configured with my GPS+1PPS (working fine). I
also have several servers configured (^server in config). For the most
part this has worked as expected/documented.
I added a few servers yesterday and noticed that they showed up as
symmetric active in 'ntpdc listpeers'. My understanding is that is what
should come up if they were configured with peer statements.
Looking at tcpdump, and after a fresh restart - I see that I am the one
setting symmetric active flags in the first packet (!!). No idea if this
is related, but these packets also come out as NTP v3 (as oppose to v4 for
all my other configured 'normal' servers).
On a fresh linux VM with a standard distro ntpd (Ubuntu 12.04) with these
two problematic servers configured, I get expected behavior (i.e. client
mode packets @ NTP v4).
I'm running 4.2.6p5 on x86_64 Linux.
I can provide more information (i.e. billboard or conf snippets) if they
Thanks in advance and happy new year.
