Channels editing

Hi,
I’m a new user of Kodi and TVheadend PVR.
I manage to setup a stream and receive some channels and groups.
Some of the channels are adult channels and I have de-active them in “channel manager”. Since these channels are also included in the different groups I also removed them from all groups.
My problem is that after restart of Kodi they returned to the groups and also get channel number 0 since they are de-active.
Why can Kodi remember that they are de-active but not that they are removed from groups?
Thanks
