Required type file on editing

Hello,

First thanks you for you’re really nice plugin !

i use you’re plugin to create custom post type from front end. But my CPT has a field type : file. this field is required.

It works fine when i create a post type, but when i’m editing an existing CPT the fields is still required while i have already a document link to that file field in my database.

Do you have some ideas without delete the required attribute ?
