rEFind_x64.efi is showing inside rEFInd?

Few weeks ago installed my first Linux distro, Mint and managed to set-up rEFInd with it. Then I decided to switch to Pop_OS. I formatted the partition that I had both Mint and rEFInd on and installed Pop instead. Since rEFInd got unistalled, I installed it back using

apt install refind

, the same way I did when I was on Mint. But then I got this problem. After a successful install, **I rebooted to rEFInd to find that it is showing rEFind_x64.efi as a possible boot option.**  **Once I hit enter, it booted into my old, customized rEFInd that was stored in the deleted partition along with mint.**  When I tried to take a screenshot in rEFInd suing F10 I got this error.  I can boot Windows from both, but Pop only works in the second (the old one that should not exist). I already tried unistalling and reinstalling, didn't help. **Does anyone know where that rEFind_x64.efi is stored? Any help is really appreciated :)!**
