Try adding the full config stack and see if that affects it.
--config-file=/etc/st2/st2.conf --config-file=/etc/st2/st2.docker.conf --config-file=/etc/st2/st2.user.conf
At the least you need to use st2.conf and st2.docker.conf as they hold parts of the total config, unless you populated overrides into st2.user.conf

Possibly related, may not be.
