Odd Issue with Author Wordcount Plugin

Hello. I’ve encountered a strange issue with my Author Wordcount Plugin. I added a new title the other day, not realizing at the time that I had entered a / accidentally, so that instead of reading The Pharaoh’s Destiny, it reads The Pharaoh/’s Destiny. I just caught it today when I went to update the count. However, it won’t allow me to change the title and update, nor will it let me delete the title and start over again. Can you tell me what I’m doing wrong?
