Hi @brunoskyny
Do you use DOI public identifier plugin in OJS?
What is your DOI registration agency?
When any DOI metadata changes, the DOI should be updated i.e. registered again.
If you are using the DOI public identifier plugin in OJS, you can use one of the export/registration plugins to deposit DOIs (metadata) to your agency (Crossref, DataCite, or mEDRA).
Best,
Bozana
