I believe I have the same issue as the OP. In Wix Editor this worked fine when my header was set to “freeze”:

In Wix Studio it does not work. I pin my header and then scrolling to my anchor is now not offset by the height of my header. It makes all my section titles disappear behind the pinned header. Super annoying. Any idea of a workaround that does not include setting massive margins that will make the site desing not look as good?
