Additional information
It looks like they forgot to update the reading mode and the reading mode needs a separator “|” to read the resolution 
works fine, but edit mod work fine without separator. Teach reading mod work with unnamed images
P.S. In edit mode, the image rendering breaks if you erase the height and leave only the width
