Dont know if it PHP 7 problem, but!

When i try to create a screen with a lot of graphs (everything about network for example), in edit mode everything is fine. But when I switch to normal view mode - some graphs changed!
Also, i saw the situation, when i add two graphs for different servers with same name (network traffic for blablalba gigabit adapter) all of them shows S_NO_ITEMS_DEFINED message... BUT! there is correct data in edit mode.

Whats wrong?

Need some additional info?
