It's because the "You have paid a total of 0.00029863 BTC" includes both your earlier "evil fee" payment (which also gives credit toward copper membership) and your more recent larger payment, but the former has zero confirmations. You have to wait for that transaction to be confirmed as well so that the total amount has 1+ confirmations.
I paid that upon registering back in 2021 for using a VPN, that had confirmations back then I always send decent fee'd transactions. Maybe since it has been so long it got mixed up somehow? The wallet address I was given to pay for copper only had the 1 transaction going to it from my copper membership payment.
