Azure Pipeline cannot detect test item in Group under Execution Plan

How to identify the test item in Group under Execution Plan.

I built a Group in Execution Plan for the purpose of regression testing scenario.

In Group, I associated every Keyword Test as "test item" and flagged "test case" matching with Azure Devops's test case under test suites in test plan.

But when pushing to Git and pipeline running, above test item cannot be detected. Why? In [search for test cases], it sets to "search for test cases"
