Using Sevagoth's shadow when reaching the 30 kill target at the end of the master rank 17 test doesn't end the test

[TheG1nger0ne]

When doing the mastery rank 17 test using Sevagoth I finished the final 4 or 5 enemy's with sevagoth's shadow and stayed as the shadow when the target was reached. However, it did not automatically end so I wait till the end, still in sevagoth's shodow, which lead to me failing the test.
