When listing the available test case trackers for saving, the AI Test Case Assistant uses the default Verifies field. Ensure that a reference connection is established between the requirement and the target test case trackers through the default Verifies field.

For more information on reference fields and details on connecting requirements with test cases, see Configuring Reference Fields for Trackers and Work/Config Items and Linking Requirements with Test Cases in the Help Center for your corresponding Codebeamer version.
