All my own presets are gone?

The new media bay only shows Factory and Official Addons. I have made hundreds of presets and before they just showed in the dropdown menu which has now been replaced by this Media Bay monstrosity. All I can see is an import function but that is useless as it’s literally 1 by 1 and I also have several third party banks so thousands that should be showing under User but it is empty

Also when I browse to them in the file menu and load one from a folder, the previous/next buttons don’t load the next one in that folder, they load the next one in alphabetical order from factory presets - it seems User content has been deprecated in favour of Steinberg authorised content
