When I scroll down and come back up via scrolling the below happens

Hello,

Apologies for the Inconveniences caused!

Unfortunately, this is a Known Issue when Parallax is enabled on Revolution Slider. Deleting the following code in the JS Settings will fix this issue:
[ch_pre type="js"]parallax: {
type:"mouse",
origo:"slidercenter",
speed:300,
levels:[2,4,6,8,10,12,14,16,18,20,22,24,49,50,51,55],
},[/ch_pre]

Hope this Helps!
