Odd OpenVPN behavior

I created an OpenVPN connection which will connect successfully to the server:

For some reason, the Stop button doesn’t end the connection. The UI will indicate that it is stopped, but if I navigate to another page then return to the OpenVPN section of Luci, the connection is still running. A quick check of the external IP address confirms this. Disabling the connection has no effect. The only way to end the VPN connection is to disable the service in the Startup page.

Is this proper behavior of the OpenVPN service? If not, how do I ‘fix’ this?
