Advance form edit not working with post preview

You can see there is no question and answer in this link while https://sportmanagementhub.com/?p=318080 if you check this link it is showing content, you cant check link because it is for logged in user but i am sharing screenshot what it is showing after logged in, so my question is if I edit and save as draft it showing content in question with public post preview link but if I am editing with frontend its not showing content, can any one help ?
