You're right. It should be fixed now: revisit the promote page. Sorry for the inconvenience.
The system was confused because years ago you paid an evil fee, which gives credit toward copper fee, but it was never registered as having more than 0 confirmations, and then in the intervening years the wallet containing that address was taken offline. I think I fixed it so that this shouldn't happen anymore.
Awesome, it works now! Thanks a lot for the help, I appreciate it. No problem at all, it has been a long time haha. Problem fixed, mission accomplished, job done, all good!
