Map Manager and Level Display not in synch

Hello Experts, 

When layer is turned off in Map Manager, corresponding level is still turned on.

Due to this there are two issues encountered:

1. This makes map model slow. Because when Level is turned off then map display is faster. 

2. When feature scan is performed for layers which are turned off in Map Manager, all features from all levels (turned on) are scanned. 

Please advice, how this synchronizing can be achieved. ?

Thanks
