I have a shared folder called “Foldername” that shows up on another computer as “Foldername-2”

Question

I shared a folder on my computer, called "Foldername". My account on the computer is UserA, my wife's account is UserB. I gave UserB read+write access on Foldername, and clicked the "shared folder" box.

On my wife's compuer, I log in to account UserB, and do "Connect to Server" and select my computer. It asks for the password for UserB, and it connects. In the dialog to select what folder to connect to, it lists "Foldername-2".

I have searched both macs for anything named "Foldername" and there is only the one. Any idea what is causing this? It's not a huge deal since the folder appears to work, it just worries me that the OS seems to think there is a duplicate somewhere in the system.
