Hey Pokermind and Joeaikman, thanks for explaining and confirming. I see the problem now, this is a bug, not how it's supposed to work. We'll get on fixing that ASAP. Thanks for the report!

In the mean time I'll leave a suggestion for a workaround on your talk page, Pokermind, so that you can continue editing and uploading without waiting for our fix.
