Well, if it interests you, Cuzit, I found the problem you were having (and maybe this will help with these things in the future). I was customizing my links, just like the ones you had on your link bar. Then I noticed that when you go into the properties of a bookmarked link (right click > properties), there's a checkmark - "Open link in sidebar". I tried checking it and it did the exact same thing that your youtube vid showed. So that's how you would fix it (just uncheck the box).
