Hi @sletten_arcadia
If the users as added to Azure AD as members, they would be added to the group as members as well and not as guest. I think the blank column is a portal UI issue. I would suggest you to run below commands to confirm the same:
- Run Install-Module AzureADPreview from elevated PowerShell window, If the Azure AD PowerShell module is not already installed.
- Run Connect-AzureAD cmdlet and sign-in using Global Admin account or User Administrator account.
- Run Get-AzureADGroupMember -ObjectId object_id_of_the_group to confirm the UserType.
