Competency requirement and Grade

Hi All,

I defined comptency requirement for a position X.

In the competency requirement window I defined low and high level of  skill "COMUNICATION", and a grade( for istance 1).

I defined  another low and high level  of  skill "comunication" but with another grade ( for instance 2).

When I create a standard appraisal for an employee (that has the position X and  grade 1 in the assignment window) I see two skill:

COMMUNICATION -associate with grade 1

COMMUNICATION-associate with grade 2

 in the competecy section.

Why?

I expected in the standard appraisal , competency section,  another behavior: I expected I have just one skill, COMMUNICATION -associated with grade 1 ( that is the grade assigned to my employee).
