I deleted your code but I can’t backup the previous code.
I want the sticky menu under the logo and the title of the page/post must have a sufficient padding from the logo and menu.
Anyway probably the logo is problematic for its dimension.
In alternative I consider a desktop/mobile version as your site:
In the first line
-Mini logo on the right
-menu stick in mobile on the left
-social plugin in the center
-logo on the same level of social plugin
-menu in separated line under
