Why do the firewall policy and reinstall preview show different address names during installation?

FortiManager uses a feature called per-device mapping (also referred to as dynamic mapping) to manage environments where different FortiGate devices require different values for the same object name. For example, an address object named " LAN " might represent 172.16.0.0/24 on one device and 192.168.0.0/24 on another.

When an administrator views the policy package in the FortiManager GUI, they see the common object name used across the ADOM. However, the reinstall preview generates the actual CLI commands that will be pushed to the specific FortiGate unit. This preview reflects the specific mapped value or name defined for that individual device, which is why the names or values may appear different from the generic policy view.
