parent page also blocked

Hi

I set this post to be restricted to logged-in users only :
https://www.vaudor.com/responsible-company/webinars/are-the-sdgs-fit-for-purpose-2/

Using a category : “members-only”.

It works fine, except now the parent category page is also restricted :
https://www.vaudor.com/responsible-company/webinars/

At first I thought it was because the category page contains a module displaying the posts thumbnails. However, the same module is used on the homepage: https://www.vaudor.com/responsible-company/, we do see the thumbnails has the “members-only” category, but the homepage is not restricted (which is the correct behavior)

this post also has a posts module at the bottom of the page, showing the “members-only” post, but it is also not restricted (which is the correct behavior)

So I’m at a lost to understand why the category page https://www.vaudor.com/responsible-company/webinars/ is restricted ?

I have also tried restricting with a tag instead of a category, but result is the same

Thanks for your help !
