"Members without a group" in an eForm is when you manually add a member to an eForm.
The screenshot below shows an example of profiles without a tagged group.
To remove the Members without a group and sort these profiles into their existing group, please follow these steps:
1. Click on the three horizontal lines on the eForm
2. Click on Sort Profiles into Groups on the left-hand side of the eForm Menu.
3. A pop-up window similar to below will appear. Click on Check All and then Save.
4. Once done, all profiles will now be part of their respective group.
