Mobile anchor link is not working properly.

There are 2 anchor links in the main menu that are being buggy on mobile. They are the bottom two anchors, ie lowest on the page, namely: https://www.bliss***********

and https://www.blisssa************ On my iPhone and client’s iPhones, what is happening a lot of the time (not every time tho) – is that it will go to correct spot for a moment, and then jump further up the page.
