I now have 12 High School students who are showing up as numbers instead of people: the student name and login ID for each of these students has turned into a 21-digit number. I can't tell which number goes to which student. What made their login IDs go bad and how can I fix it? They can change it in settings, but it always reverts back to the numbers instead of their names. They are in various different sections and even different courses. I'm using a Free Teacher Account, so I can't fix their profile info myself, nor do I have an admin. We are trying out different systems to see which one we want to recommend for adoption, and this is happening to all who are trying out Canvas. Anyone else run into this or know what's causing it and how to fix it?
