How to Create a Test Case?

Hi.

After clicking on Zephyr, The Test Management Bar displays and includes 'Test Case'  When I click to create a test case, it opens a jira issue/ticket, in which I select 'Test' but the windows does not change into a testing template with steps and actual/expected results.  That said, how are people creating a test case using JIRA?

Thank you,

Jaime
