Need more information, your story doesn't seem to make much sense. How can you (or why would you) reformat something you never use? On the surface, professionalism citations are definitely red flags for applications. If you can't handle medical school rules, why should a residency expect you to handle theirs? This one seems silly, but it also doesn't seem to make a lot of sense. Also should you receive said citation, your attitude towards it needs to do a 360. Own it, apologize, and state what you learned from the incident. Regardless of how silly the actual incident is, let residencies decide that for themselves based on your description.
