Center logo disappeared while editing

Site URL: https://www.itsdated.com

Hello! 

This is my first question ever 🙂

Well I had a web designer help me design this and so I think I may have messed up some code or something? 

So my logo was typically top and center and would move whenever you hover over it so I know it took some code to add the gif version whenever one hovers over the link. I was editing the "events" page's colors and all of a sudden the top logo disappeared. It appears when I edit the header and select certain options, but then disappears when I save and exit editing. 

Would anyone be able to let me know. 

Thank you!
