keine Miniaturansichten im Organizer

I have downloaded test images from the GFX100S in the Fuji .RAF raw format. They open as expected in the ACR module and in the editor, but I get the same problem as yours when looking into the organizer.

That's the first time I see an issue in the Organizer when the file opens ok in the ACR module and the editor.

Updating thumbnails does not work either.

I would post the same question again in the Camera Raw forum (link in the right part of this forum).

In the meantime, I suggest you open a reasonable batch of 10 pictures at a time in the ACR module, select all and open all in the editor. Then save a jpeg version as a version set. That jpeg will be shown as top of version set in the organizer browsing space.
