Issues with 2020.2 NTA data/reports with IPGroups

Hello,

After installing 2020.2 (fresh installation), some of the reports that used to work in the latest NTA that was not using MS SQL database but fastbit.

I can see in the SQL database that for the same IP/hostname, now there are different IPGroupSegmentID's assigned for different netflows, although there was no change in the IPGroups.

Also, some of the IPGroupID's are non-existent. 

Below is an example:

Thanks,

George
