Creative Commons Licence Information in Crossref Metadata "unspecified" [OJS]

Dear OJS community,

we have been informed today by a university library that our Creative Commons license is not included in the crossref metadata. In the metadata, the “content-version” is “unspecified”.

Here is a link to the metadata:

We use CC BY-SA 4.0 and have also specified this license in the drop-down menu in the Distribution Settings. Before the update to OJS version 3.2, this menu for Creative Commons licenses did not exist to my knowledge. We simply stored the URL: Creative Commons — Attribution-ShareAlike 4.0 International — CC BY-SA 4.0. This is also included in the metadata. Since then we did not have a release with OJS version 3.2 and did not provide metadata to crossref.

Do other journals have this problem as well?
Can I assume that with the update to 3.2 the license is included in the metadata field “content-version”?

Thank you and best regards

Something similar happened to us, what happened is that in the table publication_setting is a field called en setting_name license_Url and it was as license_URL we changed to license_Url and it worked
