Is it a new shell/module for this semester or is it the same one as you used for last semester? If it's the same one then it will more than likely be related to not being able to disable the grading feature. A way to check would be to see if grading is turned on when you are in the Webex > Setup area for the shell/module.
This is the message which displays when turning grading on and near the end it mentions it can't be disabled once enabled.
Confirm Attendance Grading
Enabling grading for Webex creates an assignment and automatically assigns a grade to every student based on their attendance to all Webex sessions that are scheduled within this course. The student must join via the Webex Education Connector Upcoming Courses Menu using the Desktop Client in order for their attendance to be recorded and calculated in the grade. This feature works well only for online-only, synchronous courses, and when you are not scheduling test Webex Meetings.
Once enabled, the grading feature cannot be disabled. Are you sure you would like to enable?
