[Akshat01082000]

after running this four jobs 

Tenable.sc Open Vulnerabilities Integration:- this will pull all the vulnerability for servicenow from table

Tenable.sc Fixed Vulnerabilities Integration:- what are vulnerability are fixed in tenable

Tenable.sc Plugin Integration:- get all tenable plugin from tenable to servicenow 

Tenable.sc Scan Credential Integration:- it will take credential form tenable to servicenow

so, this four are active true 

Tenable.sc Open Assets Integration

Tenable.sc Fixed Assets Integration

Tenable.sc Backfill Vulnerabilities Integration

and this three are active false

so if we are not running this three job so why this Unmatched Ci and unmatched ip and hardware class are created in Discovered Items.
