Set up internal link to track as outbound, not working

Hi,

Just installed this for the first time.

Normal outbound link tracking works fine.

However, I setup /go/ for internal links to track as outbound, and it isn’t tracking when I click those links.

Any ideas on how to fix this? It was the main reason I installed this plugin.
