Hi davout,
When you set the ‘dateStart’ and ‘dateEnd’ to the same value its not a logical bug that the event is not displayed, because when you set it like so the entry’s value is basically ‘0’.
In other words- it should always have a ‘starting date’ and ‘ending date’ in order to be displayed( determines which part it will take in the SmartScheduler).
Please, do not hesitate to contact us if you have any additional questions.
Best regards,
