John, I tried it again with Phillies and my random sampling turned up no duplication. Here's a recording of what I did - it's about 9 mins long and takes a bit of time between loading a couple of the pages.
I'm not sure what to do other than what you've already done with Admin. I'd just continue bugging him.
By the way, I believe you mentioned trying to use the record feature on your laptop but that you didn't see an option to save. Mine saves it automatically. So push the button to start and push it to stop, and it probably defaults a saved file to your Video folder. If that's the case. I'd share the video with Admin as I've done in the past to show what's going on.
