Tvheadend

Hi guys,

Im trying to setup my tvheadend, however I have a slight problem. After adding/detecting the muxes tvheadend found 342 services, however it wont map them. I can click the button as often as I want, and nothing happens. The channels stay 'unmapped'. Mapping manually also doesn't work, in that case when I close the browser and reopen it the channels are unmapped again. What am I doing wrong?

Thanks in advance!
