Looking at the description of the issue, its not clear, as to what could be the issue. I think there could be a data curruption in your System Manager Postgresql database.
Can you do the following to check if the issue gets resolved:
1. Restart your Postgresql database service by running the following command on your System Manager VM:
#service postgresql stop
#serivce postgresql start
Wait for 2-3 mins before accessing the System Manager admin page and checking the issue.
2. If the above step does not resolve the issue, run the following command on System manager:
#fsck
3. Once the above step completes, restart your System Manager Server completely doing a graceful reboot and NOT a hard reboot of the server ( Since this is a new install, it should not be service effecting)
4. If the issue still does not resolve, then I would suggest that you either create an online Service Request at
