Glitch in Images added as notes

The "Lists" info on the right-hand side of the picture page just says "list by", not by whom.

This glitch seems to affect the "Lists" section of images added as notes to movie lists or actor lists.
It does NOT affect the "Added to" section, that is the image lists the image has been added to.

For instance
