I'm unable to sort the log entries, I click on Move to Up and Move to Down and nothing happens.
Only the Move to Down works.
Maybe I'm missing something? I've only 4 entries, do I need more of them?
I've spoken too early...
The problem is still here, I've tried to destroy the whole campaign, downloading the JSON, sorting manually and reupload, without success.
When I click on the sorting button they all highlight and do nothing.
I've tried other campaigns and no one has the same problem.
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.
