[Plugin: TDO Mini Forms] Editing post does not work correctly

I have a form to create new posts using TDO Mino Forms, and this is working correctly.

I have created another form to edit these posts (By copying the original form and changing it to an edit form), but it is not working properly.

Firstly, when a user clicks to edit the post, they see the “Add new” form in their “My Submissions” screen above the edit form. Is this normal?

If they do not edit a particular field, it complains saying that a required field has not been filled out, even though the original text appears within the field.

Any ideas on how to resolve this?
