No need for a screenshot.
It's very simple.
If you have ChannelX and ChannelX HD from the UK in your m3u, you will choose the tvg-id ChannelX.uk for both of them, because we do not generate EPG for HD channels separately, because it would be a waste of time and resources.
Now you have the lcn tag in your xml file, let's say the #3, and because Plex takes the lcn number as channel number (which is a very odd thing to do), both of the channels will have the channel number 3.
If this is a problem for you, you have to delete one of the channels from your list.
I personally never understood, why anybody wanted to keep an SD channel when he has the HD channel.
Or you can complain to Plex
