I had an issue when I made picks/edits in two different computers. If I made pick in my office computer and then come home and make changes at home, the office pick would stand. I was logged on in both the computers. This has happened to me twice, once it helped me once I was in loss. Now I have started the picks/edits using just one computer, and I have no issues.

I'm not sure if that's the real case (admin might have a better idea), but just to be on safe side try making picks/edits using a single computer.

Cheers!!
