          "license_expression": "apache-2.0",
          "matches": [
            {
              "score": 98.91,

              "rule_url": "https://github.com/nexB/scancode-toolkit/tree/develop/src/licensedcode/data/rules/apache-2.0_843.RULE",
              "matched_text": "The [Netty] Project licenses this file to you under the Apache License,\n * version 2.0 (the \"License\"); you may not use this file except in compliance\n * with the License.

          ],
          "detection_log": [],
          "identifier": "apache_2_0-921dec4f-d240-dc2d-2900-d39127ffbeea"
        }
      ],

So there is only 1 LicenseMatch object in this License Detection. And so in the matches table it should show only that one match. And not 180 matches which are the same details repeated again and again.

we can close this, as it's fixed & available in https://github.com/nexB/scancode-workbench/releases/tag/v4.0.0rc3

The same license match is present in all files because they're unique license detections,
Earlier all of them were displayed, Now we show only one instance of this detection
