It isn't a bug.

The output of 'core show channels' reports a 'call' (which is not a
concept that is represented well anywhere in Asterisk) as a channel
with a PBX thread running. In this case, that's the two channels in
your output that are not outbound channels, i.e., the Local channels
that dialled your SIP channels.

That fact that you have two different SIP channels means that
something either performed two Originates, or you have done a parallel
Dial.
