Reminder problem with calendar

When I change the reminder time for a calendar item in eM Client it always sets the value to 0 minutes in the entry but doesn’t show 0 minutes in eM Client. So if I set the reminder time to say 30 minutes (from the default 1 hour I have set) in eM Client it will show as 30 minutes but gets set to 0 minutes in! Can you reproduce the bug?

I tried deleting and adding the account back but it doesn’t fix the issue.
