Hello,
Do we understand correctly that you need the report to only include members of the selected groups that are of the User object type and eliminate members of other types? If that is correct, you can use the below script in the report. At the same time, the Member types parameter can be removed as it is not used. It is recommended to create a copy of the built-in report and modify it rather than the report itself.
# Set search criteria
$criteria = New-AdmCriteria "user" -Expression {accountDisabled -eq $False}
$Context.DirectorySearcher.AddCriteria($criteria)
# Build the report
$Context.Items.Add($Context.DirectorySearcher)
