I still had the older version but even after updating to 14.4, the issue is still there. From my point of view, it looks like the issue might be related to the “endless scrolling” algorithm of the list, because when I get close to the end of the loaded list, the list jumps back to the top but now there are additional items at the bottom. The next jump only occurs when I am back in the lower area and am looking at items that were previously not loaded yet.
