Hi Trevor;
The status bar in your screen shot is a cumulative or additive status of all Test Case results for that Test Set. It has nothing to do with the 'state' such as In Progress, it is the Test Case results. In your example all of the results are failing so the bar is solid red. What is odd is that the breakdown shows 86% (or 6 out of 7) failing but no other results. There should be a another result listed there (total of 7 results) for all Test Cases in your Test Set (TS165). Perhaps there is more information on the lower portion of the page, which your screen shot has cut off. You may need to open a case with support to further determine why only 86% is showing in the breakdown.
