Process Control Systems SIMATIC PCS 7: Wrong values Following downloading entire Plan

Dear sirs/madam,
I am newbie and i have a trouble : My H redundant system included many blocks and CFC charts. Yesterday, i opened backup project and entire downloading the backup to PLC. After downloading, the values in WinCC ( Operator station (OS) and Engineering station (ES)) is incorrect with actual value.
This difference( WinCC and Actually) made many issue: Components, equipment of system can't start.
But when operator try to start equipments, components ( eventhough cant start), the alarm showed and the incorrect value on winCc changed to correct value ( actual value) automatic.
Now i and operator have to check one by one equipemt to update the actual value.
Please help me to explain this. What is wrong in my downloading action?
