How to return to start when we're in a form


I have an issue. Here’s my issue. I have 2 separate forms. They work one after another in the same story. The second form only has one slot. The slot is filled by a button. In this button list there’s a button to return to the main menu. After clicking that button I want to start the fist form again and also want to clear all slots.

But here when I clicking the button the slot fill with the payload of the button and it continue forward the story without starting the first form again. I wrote down a story to go back but it doesn’t recognized the intent here and fill the slot with name of the intent. How can I handle this issue? Can anyone help me?
