What issue do you have?

At first, I was perplexed why many of my set alarms would not go off. Recently, while incrementing the date to the next day (will recurring alarms ever be implemented in Joplin?) I noticed that after saving the new date, it would actually revert right in front of my eyes!

That seems to be the problem, as far as I can tell.
