@alycea If you have added the quiz to the module, and it does not show up in the list of potential requirements for module settings, I would check with canvas support. If you are not finding the quiz in the list to be added to the module, again I would would check with canvas support. Neither of those possibilities reflect normal behavior.
As long as you are able to get the quiz into the module, if you have turned on sequential order, students should not be able to get to items without a requirement until they finish the requirements set before that item. Students will be able to skip the quiz and move onto the next item if you do not make it a requirement, however.
