No individual show artwork with M3U source?

I have a m3u loaded and a custom xml guide data loaded. I am getting all channel logos and I get complete guide info (Name, description, episode, etc)...but I am not getting any individual show logos on the "on now" screen. Is this info that is suppose to be provided by my xml/guide for each show or can i tell Channels to at least pull the individual show artwork from somewhere else? All i see in the "on now" section is the channel logos.

I will add that with my standard cable via the HDHomerun it loads all the show artwork fine.

version: 2020.12.10.1836
system: Docker on Unraid

It has to be in your xmltv. See https://getchannels.com/docs/channels-dvr-server/how-to/custom-channels/#protips

Got it. thanks!
