I need test cases which are not linked to issues (under traceability) in zephyr scale?

Hi, I was thinking to check also tests what are missing the link to jira. Tried the option above and gives me the list. But when I see the testcase, there is traceability to jira (traceability tab has Issues Coverage with jira issue). So I think this report would give the list of linked bugs in the execution. 
The option Has linked issue also would expect to be in Test Library but there is only option linked issues where is no true/false option (because would search only the exact jira ticket).
