Ok, strangely what is happening is when I set an event and then click on alert and select custom in it and then select Message with Sound and when I close it, there are 2 problems even after selecting the time, the Calendar either does not give me an alert on the set time and it pop us up a reminder always saying 2 minutes for a new event whereas the event has already passed and also there is no message with a sound when I have selected one. What happens is, it again goes back to the default setting when I try to choose the custom alert in the alert tab. Attached is the screenshot. What should I do ?
