Edit your Story is missing in the backend

Hi,
I am now in the starting phase of my crowdfunding site and am currently testing it on a test object. Title, Category, Rewards, Currency, Target, Date, Picture is there, and the project is displayed correctly in the frontend and backend as a draft. What’s missing is Edit your Story, there’s nothing in my backend!!!
Can you tell me what I need to adjust or check?
Thank you for your help, Kirano
