Sticky Header also fixes static header

Hi, I tried to setup a sticky shrinking header according to the article you provide (How to Shrink the Sticky Header on Scroll in Neve Pro). I can configure everything the same way you show it. However, in my case the part of the header which is supposed to be position: relative (the static part / first row) is within the header-grid div which is fixed so its sticking to top even though the row is configured not to do so. Could you tell me what I’m doing wrong? Couldn’t find any post about it… Thanks upfront!

Edit: Just to make clear – it switches to the correct header after scrolling down about 180px (row 1 height) correctly. It’s just that row 1 sticks to top until then.
