Tvheadend

How to solve this?

I use an xml from timefor.tv (former ontv.dk) to populate tvheadend and XBMC/PVR (openelec 2.99.1)

Most things work perfectly - BUT.
I cant get "content type" to work in tvheadend nor in XBMC.
My goal is to get the colours to work in the EPG-timeline

Example
If i look at my xml-file from timefor.tv i can see "documentary" BUT
in tvheadend web-ui its named "news/current affairs".
In XBMC-PVR this tv-programme shows up as "documentary". (as it should be)

if i try to filter by content type in tvheadend - nothing comes up at all, except when i filter by the content type "News/Current affairs"

look here.

this is a bit of my "raw" xml-file..
