There is no "fix" in Tunnelblick being worked on (or even thought of).
I didn't know that System Preferences > Network shows any VPN status (I'd love to see a screenshot), but if it does it is probably referring to the VPNs built into OS X (IPSec and Cisco VPNs), not non-system VPNs like the ones that Tunneblick/OpenVPN creates.
I think you will have to talk to the VPNWatcher people to find out why it doesn't work with Tunnelblick.
