Bookmark How to delete watched content on PLEX Samsung TV?

I am running PLEX on my samsung tv which is Tizen 2.4 and Plex 1.0(2.5.3) all works really well except I can’t see an option to delete content from within the app?
I have it enabled in the server and I am logged in as the only user with all privileges? I have to use my iphone and plex app to delete?

Is this is a missing feature?
