The top listview overlaps the bottom listview when scrolling down the bottom listview

Try the attached file first to understand my description.

When browsing down the first vertical listview (with the items "0", "+5", ...) with the up/down arrow keys, the top horizontal listview is temporary overlapped during the scrolling animation (around 100ms) then permanently overlapped when reaching the final item.

Furthermore, if the first item (item "0") of this listview is not displayed because the listview is scrolled down, and pressing the right arrow key, the newly displayed vertical listview display the old elements ("0", "+5", ... and not "Type1", "Type2", "Type3") but only the first 3 elements can be browsed, and also the contents of the current item of the top listview changes correctly.
