Numeric rating must not be visible in the performance document ratings.

We are using calculated ratings via Fast formula to calculate the performance goals & overall summary section ratings in the performance document. For this we have specified numeric ratings for each rating levels. The numeric rating is further used in review points to describe a range. Now when the manager provides the star rating in the performance document, the section ratings are calculated using numeric ratings in the fast formula and the final rating is displayed based on points range metrics. The issue is along with the final rating description, the numeric rating is also displayed inside a bracket.
