`GithubActions does not show some attributes of the context object in the label in the result view

Summary.
We configured an Action to display attributes in a GitHub object in the Step of GitHub Actions and executed the job.
When we checked the results on the GithubAction page, some of the results were not displayed.
Please let me know if there is a workaround.

Details.
After checking the results on the page, the following conditions were observed.

  1. The head-label for each Action should show the attribute value of the context, but it shows a blank value.
  2. The log contained in the Action shows the value.
    I checked the documentation, but could not find a way to work around this situation.
    Please let me know if there is a solution.
