Shows module: episode's info overwritten by main feed

Hi, I’m quite new to podlove, but already a big fan. Thanks for the great work!
I’m using both the publisher and the player 5 on a self hosted system without support by the podlove CDN.
Currently, I’m struggling with the shows module: show information (title, image) in the player on an episode’s page are overwritten by the main feed. When I use template tags like episode.show.title or episode.show.image, I get the correct data (i.e. data of the show the episode is in, not the main feed), but I can’t pass it to the player.
Is there a way to pass the show info to the player?

I would be glad about any help on this!

Can you share a link to your site so I can see the show context and what information is provided via APIs?

Thanks for your reply, I would be very happy if you could take a look at it. The site is https://tjabelstunj.de/ – an example for the described behavior would be every episode of the show https://tjabelstunj.de/show/ma-marret-an-hauke-uubt-suufa/ (for example https://tjabelstunj.de/suufa-023/), where cover image and show title are taken from the main feed (title: ‘tjabelstünj’) and not from the particular show feed (in this case title: ‘Mä Marret & Hauke üüb’t suufa’).

I’ve added some template tags for testing purposes to see, if they would show the show details. They are hidden below the player:
<!--
template playgorund - check for this show's template tags
This episode is part of the Show: {{ episode.show.title }}
//-->
{% if episode.imageURL != null %}
<!-- Episode img URL {{ episode.imageURL }} //-->
{% endif %}
{% if episode.imageURL == null %}
<!--
Podcast img URL {{ podcast.imageURL }} <br>
{{ episode.show.title }} Show img URL {{ episode.show.image }}
//-->
{% endif %}

and would return the wanted information:

<!--
template playgorund - check for this show's template tags
This episode is part of the Show: Mä Marret &amp; Hauke üüb't suufa
//-->
