Alpha. I see you posted this message 4 hours ago.
The vote weight was a new feature added this morning. I believe that the weight % box was displaying before the backend code was put in place. The vote weight box was not supposed to display until all code was ready.
Since about an hour ago the weight feature has been fully implemented. We have had several testers confirm that it has been working correctly. Could you please test again and let us know if you experience any issues?
We profusely apologize that you spent more voting power then you intended to.
Thanks, I have tried again and it seems to be working now :)
Glad to hear it!
