I created a birthday event for my sister's birthday that is coming up on the 27th. I went to go edit the event to add images of my sister when she was younger, and when I did that, my event date change the second I clicked on the edit button. At first I did not notice the date change and went ahead and saved the event. After that, I noticed the change in date, so I did a edit again, and change the date to the correct one.
Not sure if this is a glitch or not? No big thing though, I know to check on the date the next time I do a edit. As it is now, anytime I click on that edit button it will change the date.
