catch fullscreen pro 2.2.1

hello and thank you. i'm an amateur user. i completed setting up my website. now, i'm unsure why/how: but i can see an image icon in the background of my website, behind the header and content as i scroll down the page. i don't know if i changed a setting and if i did, i don't know how to fix it. also, when i check my website, the landing page header image is visible---but sometimes the image header stays until i scroll down---but other times the image header page is briefly visible then the page automatically scrolls down to the content all by itself. i want website visitors to scroll and not be automatically scrolled. i'm very new at this, and a little confused and intimidated by this type of work. please forgive if i don't use the correct language to convey what kind of help i need. thank you. i appreciate the time, effort and support. this is my website[http://twolittleredballoons.com]
