Private Videos not moved to object storage?

We have found that « private » videos are not moved to object storage. Is this a bug? or is there a config that affects this? If we make it public, it is in object storage, but it we switch it to private - it moves back to local.
We need the private videos in object storage, is this possible?

Thanks for any insight!

How do you see it’s moved back to local storage?
