Regarding upgrading Supporter Edition

I recently upgraded my Standard Edition to the King of Faridun Edition. However, for some reason, the prices for the other editions on the website haven't been updated and still show the same upgrade cost as if I still had the Standard Edition. This is confusing because in-game, it displays a much lower upgrade price for the other editions. But if I try to upgrade to a higher edition, I can’t purchase it for the in-game price since it redirects me to the website, where the higher price is displayed. I don’t understand why this is happening. What should I do?
