Dc:rights creative commons metadata

Hi
Currently we have the version 3.1.2 of ojs and when we review the metadata of the articles we see the following on the label rights

<meta name=“DC.Rights” content=“Copyright © 2019 Magazine name”/>
<meta name=“DC.Rights” content=""/>

but the rights label should be something like that

<meta name=“DC.Rights” content=“Copyright © 2019 Magazine name”/>
<meta name=“DC.Rights” content=“http://creativecommons.org/licenses/by-nc-nd/4.0”/>

how do I add the creative commons license to my page
