I'm using the normal tracking code from Piwiks admin page with link tracking enabled. Outgoing links are normally recorded by Piwik. All fine.

But I also have links other than HTTP or HTTPS on my website, for example, rtp: // ... These links will be logged, but misrepresented on the Piwik page. They all appear as a link to the Piwik Dashboard. In the visitor profile these links as shown as "Page URL not defined". Screenshot attached.
