VPN Routing Policy

I'm trying to route all my transmission traffic via vpn, but it seems like this option isn't working.

How can I use it to route only traffic from transmission which I have running on my R7000 itself?

Extra info:

I'm not actually using my R7000 as a router, it's set up as an access point behind my router modem, it's not even acting as a dhcp server.

Is there any way to do what I'm doing without advance config?

I did test it with no extra config and it seemed to work when I used a test...
