Client Status issue on Primary

[zainulpatel]

I have a following issue.
When i check for client status under "All systems collections" in SCCM console on Main Primary Site it shows as "Yes"
But when i check the same thing on Child Primary Site it shows as "No"
Now the status which is shown on child primary site is correct and the one on Main primary site is incorrect.
This same thing is seen on other child sites as well. There are systems which should be showing as "no" in client status show as yes on Main Primary site..

Please assiste how can this be corrected ..Just to add the Clear Install Flag is set to "No" on Main primary Site.
