I duplicated page stoly at my website. New pages are 2rzedy and 4 rzedy.
At new pages at properties panel for any dropdown, button there is nothing inside. At "mother" page 'stoly' i have lots of function onclick and onmouse etc. All those function at new site are in code but i dont see them in properties panel. Pages works corretcly but i'm not sure now which functions are there and if everything is ok
