UMBRELLAS DIRECT AUSTRALIA review for Sticky Cart+ Fly Cart

Please help. I Installed your plugin but had to remove it as it didnt do what i needed it to do. The problem is now, even though i deleted the app properly, there is now a white transparent sticky header on all product pages which wont go away and wont even let me scroll down on ALL of my product pages. Please help, I was hoping to literally launch my store tomorrow.
