Klein Rj45 Crimpers Failing Qualifier tests.

So I have a pair of Kleins (VDV226-110) Rj-45 crimpers. After a job all ends were tested and they all passed using a kleins VDV526-052 tester (simple end tester). There are no visual indications of a bad crimp.

However when we started having network issues with about 50% of runs and brought in the qualifier (Fluke), it turned out the Rj45 ends were indeed the issue.

Is there anything I can check on crimpers that would cause this? or should I just ditch them out of an abundance caution and go with a different brand? A little disappointing $60 crimpers perform this poorly.
