Remove Branding after Payment

Hi, I have upgraded to the bronze subscription to remove the branding. However it's still on my form even after I've unchecked the " Show "Powered by JotForm" on my forms". It's still there. Any recommendations?

Apologies for any inconveniences caused. I have cleared your form cache and the banner should not be displaying now.
