Why do i have 2 dashboard Icons in applications folder?

[Atlguns]

Anyone know why i have 2 dashboard icons in my applications folder.
One just says dash board and the other says dashboard (original).
BTW I am a brand new to mac.
Just recently bought the new 2011 15" with 256 SSD, and just love it

odd, anyway check what version they are and delete the older one if there is a difference.
