Dear Maintainer, I have successfully reproduced this bug on the same version of the package.
However, the bug does not occur in all situations. If an event is created by only clicking a day in the calendar, entering a name for the event and clicking the "add" button, the event is set to the correct day. However, if the "edit details" button is clicked before clicking the "add" button, the bug occurs. The bug also occurs when editing an existing event, as reported in steps 4 to 6 of the original bug report.
