Bug: 'My Watchlist' jumps over 'Plan to watch'

I cannot view my Plan to watch section of the Watchlists anymore. When I reach that section the page jumpes to a blue screen (on laptop) or to the far bottom of the page (on mobile). With the Laptop; depending if I scroll down or up, next it either goes to 'dropped' or 'completed'. The same happens when I try to go up from the  bottom of the page. (I own a Macbook Air and an iPhone)

I can't reach the Watchlist when I'm not logged in.  In Firefox it doesn't happen the exact same way but it still jumps around the page while I'm scrolling. For example if i'm at 'plan to watch' and scroll up, it jumps to the top of the 'completed' section.
