If you have a backup disk connected, and it contains a full backup, it will show both copies.

If you don't have a backup disk, use a utility to delete the LaunchServices cache and reboot.

where is that launchservice cache file located at? and can i delete it using terminal.app? i want to be sure i don't delete the wrong file.

oh and i dont have no backup disk connected.

You want to get OnyX. In the maintence tab there is an option to reset LaunchServices.

As a side, it doesn't matter if you have a backup disk connected or not. If you've ever made a backup with something like SuperDuper the duplicate app is referenced in LaunchServices even when the disk is not connected.
