Component field not populated in Test Summary report

I created a new project in Jira to play with Zephyr for Jira (both Jira and Zephyr are cloud versions).

I created a field 'Component' and added that to the Test issue type. I populated that with a dropdown list of 50 values.

I have created 2 stories and 3 tests in this project.

The Component in the Test Summary report shows that none of the tests have a value for that field.

How do I solve this?  

Thanks!
