old form error on the admin backend

Hi,

I’m having an issue when i try to edit my old forms, when I create a new form everything is fine but the on the old forms it showing an error with all fields on the “Reference Name” field.
i created a unique name for every field and the errors is gone! however, only the submit button no matter what I do its still showing an error so I can’t save the changes!

also one more thing, when I duplicated the form I got errors on the plugin

Thank you
