Thanks. I also wondered, then I read that the version will show after I produce my first block.
After that gets broadcast, you are up and running as a witness. You can check that you are enabled somewhere like https://peakd.com/me/witnesses. The green ball means that you are enabled. Your version will not report to the version that you are using until you sign your first block so don't worry if it says 0.0.0. Just get the word out there that you are being a witness and get more votes.
