Fixed header not resizing properly in relation to logo

Hello,

I have configured the header as “fixed header with social media icons and additional navigation”. Previously I had configured the header as “small fixed header”. This previous configuration worked perfectly with the max height of the header at the largest setting corresponding to the largest dimensions of my logo – approximately 128px tall plus a little margin or padding above and below the logo.

However since I enable the “fixed header with social media icons and additional navigation” the max height of the header at it’s largest size is now out of proportion with the largest size of the logo leaving about 30px of “blank” space below the logo in a way that makes the header feel unbalanced.

How can I set the “max-height” of the header so that it remains more proportional to the logo?

Here is the demo version of the site:
