Issue with smooth scroll not aligning, using fixed header

Sorry to resurrect an old topic but I am having a new issue with this. I have a position:fixed header that starts off display:none but through an interaction (when you scroll past a certain point) it slides down into view. I had used callmevlad’s suggestion and set the element to have a HTML5 tag and everything was dandy with my in-page linking.

However, recently the header has reverted to covering the the top portion of the section of the page I am trying to link to. As far as I know, nothing about the page has changed but this feature has stopped working and I am bamboozled as to why. Any ideas?
