DayPilot Event Links do not point to accurately

Hi,

I am using DayPilot Event Links in my system to show the dependencies oh the workers. But i found that some of the pointer is not pointing to accurate events. Some of them are working normal but some are not.

private void DrawDependencyLinks()
{
DayPilotScheduler1.Links.Clear();

DayPilotScheduler1.Links.Add(personA_ID, personB_ID);

}
