In the past when I've made a key, I would fill in all the answers, click the box at the top to select all the questions (all the same format, multiple choice) hit edit and modify. I would be able to change the value of all the questions at once with no problem. Now when I do it this comes up
Editing 40 questions
The selected questions do not share the same configuration. If you want to change attributes such as the question type or choices, you must reset the questions so they have the same configuration.
NOTE: resetting the question configurations will not remove aligned standards.
