Groups Listed in the Reports dont exist in AD (4277955)

Running the built in reports from Report Manager, eg Domain Groups and Members, When Selecting 'Include the following Domain Groups' the lists shows groups that don't exist in AD.

Why is this showing these groups?

The Groups can be created from Exchange specifically as a Dynamic Distribution Group, A user can then be added to that group. When an AD Discovery is run it will identify the user being a member of such a group and therefore list this group in the Report Manager, even though In AD this group doesnt exist.

Example Office-Test

1. To check the Type of Group this is
2. Open SQL Management Studio and find the Enterprise Reporter Database, expand tables and then locate the table
3. DBO.tblAccount Right click and slect top 1000 rows, if there are more than 1000 rows change the query to 10000
4. From the results export them to a CSV file
5. Open the CSV file and search for the Groupname Office-Test (make sure its spelt exactly as its seen in Report Manager)
6. example result - -********************,D,,DDG,2016-08-15 20:08:49.773000000,False,DOMAIN,Office-Test
7. The String DDG indicates this is a legitimate group from Exchange and is a Dynamic Distribution Group
