Hi,
Thanks for using our plugins. I can help out here.
This is the settings I found work to create as you like: (8am start time for the middle event)

However, I did notice an issue and that when I change the event time it uses utc 0 and not the timezone I was in.
So although wrong, this is the actual settings I used to get the times correct on the East Coast of the U.S.: (Middle event 3am start time due to -5 hours from UTC 0 )

Do you know what your timezone is in relation to UTC 0?
You maybe to convert the new start time using that offset.
I have created a bug report for us to address this, but can help get this working for you too by working on that offset.
Let me know if you have any follow up questions.
Thanks
