CVEs does not fully import from NVD Library

Hi everyone, I'm new to Zenwork Suite. I attempted to configure the CVE Subscription last week and link it with patch management. The subscription logs looks good when syncing CVEs from the database.

After the synchronisation was complete, I went to patch details page and noticed that the CVE ID were not clickable and without summary info. Only some of the supersedes patches's CVE ID is clickable and show the summary info. Is there a way to troubleshoot this issue or have I misunderstood something? Thanks.
