Picture format in media folder is always square and less preview options

Hell there,
I was very happy to see a lot of configuration options on how the preview pictures in the media section were customizable some releases ago. With the current release I can‘t select the previews to be square or wide format.
Even worse is the square format when watching the pictures in media. They are all in square format and the only way to see them in the original, wide format is to download them each…

Please let the pictures open in the correct (wide) format as bevor, it looks awkward to see them in square format, missing a lot of the content.
