Copying Admin Users Deletes All But 1

I was setting up a remote dude server to use for some distant probes. So I brought up the dude and selected all the Admins listed and used the Copy button. It deleted every user but 1. After restoring to an update I had thankfully just taken I tried it again. It again deleted all but 1 user, a different one this time. So I had to restore again. I am on version 3.1. Any idea what is causing this? I wanted the community to know so that maybe you guys can fix it. Awesome software though! Just gotta root out a few bugs. :wink:
