Problem with built-in and custom prev/next buttons

Hi all,

For my course created with Storyline 2, I switched the previous and next button off from the standard Storyline player. This is because I use custom-made navigation buttons. But something strange is happening when I leave and re-visit for example my multiple select page. When I revisit this page, the back and previous buttons from the standard Storyline player do show, which I do not want. Any ideas on how to solve this?

Thanks a million!
