I can see two issues - one already explained in my earlier post here and is a timing issue when EPG programs are added without an Original Air Date being set initially.
I see also there was an error on the episode titled “09-21-2020” where the original air date was set as 18 September. I have referred this to our provider and also asked for Original Air Dates to be set when programs are added rather than days later.
I expect all these issues to go away once we migrate to a different EPG provider as mentioned here
