Quiz retake textbox disappeared

Community Explorer

I created a quiz and students were asked to answer one of 4 writing prompts. I gave them one attempt and checked their formatting when they submitted it. If the student did not follow the correct format, I gave them another attempt to go back and retake the quiz. ONE of my students, only ONE does not have textboxes on her retake. I have tried logging her out and back in, logging in to a different computer, nothing I do will make those textboxes appear. They show up on every other student who is given a retake. I even gave her a few more attempts thinking that would help-it did not. Now, when I go to grade her assignment, it won't allow me to grade the one she submitted. It keeps changing her grade back to the icon. I am at a complete loss here.
