Tvheadend

On my TVHeadend Version 4.1-373~gcb5f6a1

The DVR Upcoming/Current Recordings web page has an episode field which is empty. The XMLTV data has the episode info in it, so this field should be populated.

My recordings folder shows the episode inside the filename so TVHeadend must know what the episode is.

i.e. "Wanted Down Under Revisited.1-10. Desperate for a more balanced life, the Patons spent a week in Adelaide to find out if emigrating could offer the answer. But were they able to make the move for good_ [HD] [S].ts"

Any ideas why this field is unpopulated and should I be able to reject duplicate episodes?

Thank you for any help.

Pete
