RDG + Per-Request Policy not working

In our webtop we publish remoteapps and remotedesktops. At the moment Im trying to implement a per-request policy to look at certain urls.

To make RemoteApps and RemoteDesktops work we adding a RDP-RAP to our Access policy. But as soon as i add an empty per-request policy to the VS, our users cant connect to the RemoteApps nor the RemoteDesktops. In the APM log Ive found this:

Is this a supported mode?

Any suggestions to troubleshoot this futher?
