This bar displays the percentage of the NXC’s PKI storage space that is currently in use. When
the storage space is almost full, you should consider deleting expired or unnecessary
certificates before adding more certificates.
Edit Double-click an entry or select it and click Edit to open a screen with an in-depth list of
information about the certificate.

Subsequent certificates move up by one when you take this action.
