There has to be some error because a VPN works in a way that masks your IP address. If you can still see the IP address after connecting to the VPN, then it mean the software isn't configured correctly. You will need to contact the developers of the application or use something else like TunnelBear. I have used TunnelBear for a very long time and it works accordingly to the online specifications.
