@dee077 thanks for your contribution. We should update all the i18n files, such as CN, FR, etc.

Since we’re reaching RC this week and this issue must be fixed by the end of the week, please let me know if this is feasible. Otherwise, we can take it over.

-        "CA_CERTIFICATE_TOOLTIP": "Provide a PEM-encoded CA certificate to verify the registry's TLS certificate. Leave empty to use the system CA pool. This field is only available when 'Verify Remote Cert' is enabled.",
-        "CA_CERTIFICATE_HELPER": "Optional. Paste the PEM-encoded CA certificate here to trust self-signed or private CA certificates for this endpoint. If left empty, Harbor will use the system CA pool."
+        "CA_CERTIFICATE_TOOLTIP": "Provide a PEM-encoded CA certificate to trust additional CA certificates for this registry. The custom CA will be added to the system CA pool, allowing Harbor to trust both system-signed and custom-signed certificates. Leave empty to use only the system CA pool. This field is only available when 'Verify Remote Cert' is enabled.",
+        "CA_CERTIFICATE_HELPER": "Optional. Paste the PEM-encoded CA certificate here to trust self-signed or private CA certificates for this endpoint. The certificate will be added to the system CA pool, not replace it."
