"File history" table on https://commons.wikimedia.org/wiki/File:Orsip.png says user is Magdalenacicha ; https://commons.wikimedia.org/w/index.php?title=File:Orsip.png&action=history says the same.
Please provide steps to reproduce the problem and the expected username.

I can confirm that. Likely a caching issue because the user has been renamed:
