Sometimes, the same individuals are invited to assess multiple Subjects.
Typically, when you enter the same individual multiple times, the system handles this seamlessly. However, it can happen that one of these entries was created with an incorrect email address. When you attempt to change it, you will be asked to combine the listings, i.e., merge those records into one. Simply follow the system's prompts.
The Merge page allows you to choose the correct names and other attributes to apply to the merged listing. Carefully review the suggested options and select the correct ones.
When you click "Save", the two original listings will be replaced in the People List by the merged listing.
