After adding event with Recurrence Field itemIds() API is not returning proper events

After adding events with Recurrent field itemIds() API is not returning proper events.

But If i restart calendar it shows proper events. Please find the logs for both normal and abnormal case.

In not working case.
After adding recurring event.
EDS refresh the model and All recurring events are added with same start and end date with which original events was created.

Once this is done,
EDS is reloading the model again and this time it does not return any event for the original start and date time with which we created the event.

Please find log snippet below.
