Divi Website Issue Using QuickieBar

I have a new Divi website and I am using the Pro version of QuickieBar. I had another website builder "try" to make the QuickieBar appear at the top of the pages and must have "hard coded" the divi header and divi navigation bars so they appear about 1 inch below the QuickieBar. The issue occurs if someone closed out the quickiebar or if I don't need the quickiebar on the top of any page, the header and navigation are in the wrong place. 1) I need my divi header and divi navigation to appear in their natural locations at the top of the pages. 2) I want to make sure that the QuickieBar works on both desktop and Mobile (right now the mobile doesn't work). 3) I am happy to get rid of the QuickieBar and just create a button using Divi if that is the best solution.
