TV Guide Showing New Episodes as Repeats

[Melawen]

Having used Plex intermittently for the last year or so I recently decided to give Jellyfin a try as Plex has not been great at transcoding my Blu-ray rips, whereas Jellyfin just seems to take it in its stride.

As I have a couple of HDHomerun tuners as well I wanted to also switch the PVR to Jellyfin.  This has taken a little more effort as I use Schedules Direct for my guide data and there is apparently a longstanding issue with this and Jellyfin.  I have, however, found a workaround using a Python script that grabs the guide data from SD and converts it to XML so that I can import it.  Everything is fine there but, per the title, Jellyfin is marking new episodes as repeats; not everywhere but definitely on shows that I know have not been broadcast before.  As an example from tonight's guide:

   

So from this list, the Alan Partridge, Graham Norton and Mitchell and Webb episodes are definitely new.  I have looked through the XML file and there is nothing there that shows any episodes as repeats and I'm honestly not sure where this is coming from.  It is entirely possible I have missed a setting somewhere but I cannot see anything obvious from hunting around the menus.

If anyone can point me in the right direction I would be very grateful.

[Edit]
I forgot to add, I am using Jellyfin 10.10.7 which is installed as a Docker container on my Unraid server.

After speaking to ChatGPT and providing some extracts from the converted XML it pointed out that there are tags for <previously-shown start> on some shows, for the same day, that might be causing Jellyfin to incorrectly mark episodes as repeats.  There are also tags for <episode-num system="dd_progid"> with the unique IDs though I'm not sure they are as helpful.

As an example, here are three shows on this evening that are all new episodes but are marked as repeats in Jellyfin:
