On and Off "Powered By Dolphin" tab on website

I keep getting On and Off "Powered By Dolphin" tab on website even after I purchased and am using a valid Ad Free Dolphin License, I found to temporarily fix the bug I have to log into the Control Panel and re-enter my license key and log out immediately, but it comes back after a while. Is there a fix to this annoying issue, I paid 99 for my license so why is it not AD FREE 24/7?

Any Help
