flexslider 2 showing white space around the slider on initial load of webpage and when page is refreshed? If I click on about page and go back to the home page the white space disappears.

If I refresh the page the white space returns.

I have removed flexslider 2 and loaded bxSlider instead and the exact same thing is happening?

I have checked this on different browsers the only one that has no issues is firefox?

Anyone know what causes this and how to stop it? looks pretty hideous.
