Menu scroll position mostly not correct (especially when jumping between pages)

Hey folks, I’m encountering an issue with the scroll position of my navigation. Sometimes - but not always - when clicking on “About”, the position is scrolling to some random place no the page, to a position where a Pro Gallery is placed.
And the problem also appears every time I’m on a different page and hit the “about” button, which brings me back to the home page, where it doesn’t scroll down far enough.

Another thing with the Pro Gallery is that when clicking on the “back” button on the browser which brings me back to the gallery, the scroll position doesn’t always match the position where i clicked on the gallery. And I don’t know if this is a bug or if there’s any way to fix this. Would appreciate an answer from the devs on this, thanks!
