When clicking on the Test Execution status on the Test Runs tab of a Test issue, an additional 'N/A' test status shows up

Steps to reproduce:

1. Open any Test issue that has a Test Execution associated with it.
2. Go to the Test Runs tab under the Test Details section.
3. Click on the status of the Test Execution, to open the list of available test statuses.

Expected result:

The list of available test statuses should include only the test statuses that are configured on the Test Statuses screen (Apps > Xray > Test Statuses):

Actual result:

The list of available tests statuses includes one additional "N/A" status, which has the description "Test is not included in coverage".

Additional details:

• This test status seems to be built-in Xray, but should stay hidden.
• It is not accessible through any other screen (like from the Test Execution issue, from the Test Executions tab on a Test Plan issue, or from the execution results screen).
• It is only accessible through the Test Runs tab from a Test issue.
• If you try to change the Test Execution status to this "N/A" status by clicking on it, there is an error 500 (Error updating the Test Run Status, Request failed with status code 500).
