Tvheadend

When I use Tvheadend with IPTV Simple Client, either of the following happens:
- crashes, while it's loading the channels, so I have to restart Kodi
- loads the list of channels, but with no channel logos next to the channels. Channel doesn't load, when I choose the channel
- loads two sets of the channels, so I see (for example) 'BBC One' with the logo and beneath it 'BBC One' with no logo. When it appears like this, I can watch by choosing the channel with the logo. If I click the channel with no logo, nothing loads

I've now had to resort to switch off Tvheadend, as I can watch the channels with no issues.
But I sort of miss the EPG :-(

I'm using an Android TV box (Beelink MiniMX S905 with 2GB/16GB)
