Not sure if this is a bug. I noticed that when typing in the date and time, it requires 2 digits for the month and hour. Using a single digit, the wrong time is displayed.
Type in the following date and time
![2020-03-13 08:00] -> display correct date/time
![2020-03-13 8:00] -> display wrong date/time
![2020-3-13 8:00] -> display correct date/time
Which operating system are you using? Windows 10
