Animation Direction is always to the right in Split View

When in “plan Split View”, and I use the right arrow to see the next list, there is an animation of “swiping right”. But when hitting the left arrow there is also a “swiping right” animation instead of left. Which looks confusing. It works normally when going left from the first list to the list overview, but not when switching between lists.
