Use default gateway on remote network option was always enabled

I'm using FortiClient 5.4.0.0.0780, after i connect to the host, the network setting "Use default gateway on remote network" for the fortissl adapter in Windows was overridden to always enabled. It makes my original remote connection was dropped due to this change after connection make through FortiClient.

When the connection is not yet made, I've already set the option "Use default gateway on remote network" to disable. However, when connection make, the setting is reversed.

Anyone can help? or this is bug in the new version of FortiClient?
