Events created in Thunderbird Lightning Calendar don't show as busy on my scheduling page


If you use Thunderbird Lightning Calendar and create events using that plugin, by default, events in your calendar will be created with the status "free". 

This is a bug in the Lightning Calendar because newly-created events should be created with the "busy" status by default. checks if the events in your calendar are "busy". When the event is set as "free", on the scheduling page the date & time will be still available.

Solution: After adding an event via Thunderbird Lightning Calendar, edit it and change the status from "free" to "busy".
