No episodes in podcast - can't add it to favourites

I switched to Deezer. Love it so far!!!

One thing though: i  wanted to publish a podcast via it's RSS Feed  because I couldn't find i in the Search function. (I used https://podcasters.deezer.com/  and this is the RSS Feed https://www.ndr.de/podcast/podcast5522.xml )

It said the podcast is already available - great.

However, when opening the podcast in Deezer there are no Episodes and I can't add it to my favourites.

Could you maybe look into it please? Thanks in advance
