Hi

My default photo sort order is set in Configuration to File name, A to Z.
This works correctly in all albums.
In some albums I want to manually change the sort order of a few photos.
In the Edit Album [Properties] screen, Photos sort order tab, the photo thumbnails seem to be in a random order, not the file name sequence as displayed elsewhere.
I have to drag and drop every single photo in the album to get it to file name order with the few other sequence changes needed. 

Is this normal? I was expecting the manual order screen to initially display the default sort order enabling just a few changes.

Thanks,
John
