full screen issue on iphone after scroll

I’m really pleased with the Masterslider works brilliantly apart from 1 issue I ran into.

I’m using multiple instances of the slider on a 1 page website. On the iPhone 5 and 6 when I view the site the first slider show fine (meaning it shows full screen) but as soon as I scroll down to the next section (click on projects at the bottom) the second slider is no longer full screen (it doesn’t adjust to the height) I understand that this is due to the bottom bar of IOS disappearing but is there a fix for this issue?

Everything works fine on other mobile phones and tablets etc…
