Category Banner and Square Images.

Help!

I have forgotten what I once did several times.

I need to have a different category banner and Category Image.

To See my problem go to https://www.pixelcomputer.de/shop/

If you click on a category like Workstations, Laptops or Phase One – A new page is opened and I see a category banner which is different from the overview thumbnail. This is fine and I want this behavior everywhere.

But I have forgotten how to achieve this. Like I added a new category in Laptops. If you go here
https://www.pixelcomputer.de/produkt-kategorie/laptops/

You see Laptops Auslaufmodelle 2022/2023 if you click on this, you see a scaled image of the thumbnail. And I don’t find the way to define a banner image different from the thumbnail image.

I gooled and found that there should be an Option in Edit Categories to define a banner, but its not there:
Navigate to Dashboard > Posts > Categories and edit the category. You’ll see the image upload option for the banner there. I only see one for the image but not for the banner.
In another post I found that I should go to Enfold, Theme Options and Shop Options to Enable the Category Banner there but I have no option there.

Please help!
