Replacing an image in an entity which is a specialization of system.image

Yes, I know, not an ideal situation but it is what it is now. I have an entity Country derived from System.Image and the flag of the country is the image.   Now when I try to replace that with another image using the default Mendix image uploader component I notice that it does replace the full image but not the thumbnail?    Is that a bug or am I doing something wrong?

If the image is replaced but the thumbnails is not, then I’d classify this as a bug.
