A Project in my Vault now has a Twin?!?

Our IT guy has been doing a lot of updates on our old old server and it has been restarted several times.

Yesterday something odd happened when I logged in.  One of the projects in the Vault was now listed twice!

I opened the Workgroup Admin and it was only listed once. 

My coworker is seeing the same duplicate project as well so it has to be the servers problem.

If I hide the duplicate or the original project the other one hides as well.

They are a perfect match as you take and release ownership.

So I was just wondering if anybody has seen this before.  Its not a problem but I am just a little curious about it.
