Revision History feature: the form still say in its current state

I have tried using this function and the form still stays in its current form it does not revert back to its previous form

We would like to apologize for any inconvenience. Can you tell us which form in your account would you like to revert to its previous state, please? And can you tell on which status of your form would you like to revert it to?

We will wait for your response.
