In your project you have a decorator that rewrites the url to the cdn-url when the blob not exists local. In that code a check exists `blob?.GetDefault()?.Exists == true` and the thumbnails will not have any default-image and instead named images.

Try to change your decorator for something like this

This can also be an issue for the [Thumbnails is not always generated](https://forum.litium.com/t/thumbnails-is-not-always-generated/1743)
