Exporting funding information

Hello,
I am using the OJS 3.2.0.1 version. The first article published in the journal had funding metadata, which was successfully exported to Crossref. However, every article published from now on, either with different funding metadata or not, is exported to Crossref with the same funding metadata of the first article. If someone knows the reason why this is happening, I would appreciate your assistance.
Regards,
Carlos.
