Aloha!
Your screen capture is really helpful - your entries are "stuck."
That is a persistent bug. Sometimes the order criterium is not correctly set, and two entries have the same. In the current version, this is the date string in the upper left part of an entry. On the last frame of your video, you can see that "Note sparse" and "Riepilogo 05.06.2018" have the same date.
There is a rather nasty solution: exporting the log, manually editing the date, and re-importing the changed log.
I will attach your video to the bug and prio it for Friday to look into this.
