Calendar events disappear instantly (on both iPad & iPhone)

[Adebelle]

Hello everyone. I use my calendar application for many things. Not only do I use it to record upcoming events, I also use it to record events that have happened in the past. I recently got the iPad a few weeks ago and I also updated my software on my iPhone 4 at that time. Im using iCloud, and i though all synced fine. Today, however, I tried to look for an event that I know I recorded, but it was not there. Because I remember the information, I decided to enter it in the calendar again, for future referencing. Right before my very eyes, on my iPad, the even disappeared. So, I decided to enter the information on my iPhone. Again, the information disappeared. I don't know what's going on, and this is a bit frustrating. I can only imagine what information I must have already lost. Is anyone else having the same problem or know what the fix is? Thank you for your time.
