IOS theme leaves big gap between the navbar and the first widget

Hi,

In my overview page i have a big gap between the nav bar and the first widget. This is only in the ios theme on my iphone. It seems that a div with class block-narrow block is inserted for no reason. What can be done to get rid of the blanc space

this is the yaml of the overview page
