[OJS] Unable to register Full Text PDF DOIs

I am using OJS CrossRef Export/Registration Plugin successfully register DOIs assigned manually at Submission metadata stage however, DOI assigned to PDF Galley Proofs at the editing stage are not displayed at CrossRef Export/Registration for registration.

Hi @esciencepress,

Were the successfully registered DOI for submissions that had already been published?

Kind Regards,

@pmangahis Yes, all the registered DOIs were published. Actually newly assigned DOIs firt appear in Not Deposited, when Registered, appear as Submitted. They are then appear as published as appear on the IndexPage and respective published article. Each DOI is resolve however do not appear in Deposited | Active section of the plugin.

A screenshot is attached.
