DOI is doubled in ojs 3 (DOI for journal issue and DOI for article)

Hi all, DOI numbers in OJS 3.0 are both on the journal issue and on each article in the journal. How can I delete the DOI number for journal issue?
I think OJS 2 only have DOI on the article.
thank you

Hi @Diah_Suryaningrum,

I think you can go to the CrossReff plugin settings and exclude the issues from having DOIs and keep only articles marked.

thank you for your suggestion. I have done as you told me, but the DOI journal issue is still there… so the DOI is still doubled for the issue and the article. What should I do to delete DOI issue?

Best Wishes,
