What's Wrong?

The synthesized report after a completed workflow is incomplete and invalid. The summary literally says "items 123 test", and the confirmed list only contains 3 entries, even though there were 29 confirmed findings.

What Should Happen?

Workflow synthesis report should be complete and not contain garbage.
