All recurring events create extra occurrences

When creating a recurring event that has a set number of occurrences, the occurrence occurs an extra time.
For example:
If I try to create an event for “daily” “repeat every 1 day” “end after 2 occurrences”.
The event will be display for 3 days from start date.

To Recreate:
-Create a new event with the following parameters: “daily” “repeat every 1 day” “end after 2 occurrences”
-Refresh the parent page and observe the extra occurrence

I am using dhtmlxScheduler v.4.3.0 Professional Evaluation copy.
