Hi Kayla
The first step is to contact your Totara partner and explain the problem.
The good news is that any course completion and progress data will be kept unless the user is unenrolled from the course.
If there have been users enrolled by audience accidentally then this will create a course completion record . This will probably need to be deleted through the course completion editor . Also note if there are lots of records then these can be deleted in bulk but will need someone with access to the server (Partner) to do this.
Regards
