Items dissapear from screen
In short, I've create screen with 7 graphs, everything was fine, but today I noticed few graphs dissapeared from screen. In screen builder I see empty rows, when I try to "change" cell - there appears dialog specifying item name which was there, when I push "Save" - some other random graph dissapears.
