Status for Execution Step in Test Script is Greyed Out

I have created a testcase with 1 test script (which contains manual steps). When I execute the step in the test script, the drop down box with the status of the step is greyed out. The only thing I can do is apply the status which is set to pass. I did notice that the next step in my script is a verification point and the status drop down box is not greyed out. Is this working as designed? If not, how can I choose a different status for the step?
