Why I can't revert my form to older version?

Hi, I'm trying to revert to an older version but every time I choose a version and hit the "Revert" button, it just goes back to making the most recent version the "current" version

Please try a different browser or clear your browser cookies & cache and see if that will work. If the issue persists, could you please let us know if we can make changes or we are the one to revert your form to your preferred version?

Please give it a try and let us know how it goes.
