normcdn on "Display images by ... ID cause error"

Hi,
You probably have noticed this problem. It is not related to this version, as I had the same issue in the previous version.
After I have uploaded the files, the next screen is set to ... Display images by ID (descending). Whatever I type in the title fields of the images, after I click the button apply, it reset automatically all my changes. The only way I can prevent that is to change the display images by ... to filename. In the [options] / [Gallery] / I set Sort gallery by: to filename.
Any clue ?
Thanks
