Well, everything seems to work, but I get those unexpected values when running get_witness bcn (and on https://steemd.com/@bcn). I've used git checkout v0.19.0 before building, so there should be running_version: 0.19.0 as for other witnesses. I didn't find anywhere information about this and what hardfork_version_vote stands for.
First I downloaded the blockchain and did ./steemd --replay-blockchain as recommended. Thought that something is missing and tried again with ./steemd --resync-blockchain but nothing changed. Maybe that's because I'm running only one server which is witness without seed server?
Well if your processing blocks I wouldn't worry about it too much.
