When l add more channels (local playlists) via channel manager, they get saved but get deleted when PseudoTv Live updates, l am not sure if the channel numbers settings were responsible for that.

That is similar to what I am seeing, but Ive had more success with just adding 5-6 channels at a time, then doing a clear/re-add in Kodi's PVR settings, and then doing a clean exit out of Kodi.  Rinse, Repeat.

Try v.0.2.4c let me know if you still have issues. I'm only concerned with channels removing themselves from your channels.json config... This is not normal behavior. As for m3u/xmltv channels come and go based on content availability.
