Validated Requirements still showing up in Report

 I am trying to build a report that shows all of the system specifications that aren't validated by a test case yet. In report build I choose system specification as my artifact. Then in the trace relationships and add artifacts section I choose validated by test case. In the relationship: drop down I choose "Does not exist". However, specifications are included in the report that are validated by test cases. There is no test case in the report but when I go to the requirement in DNG it has a validated by link to a test case. Those requirements also show up when I choose required with the link to the test case.
