Salary increase is not calculating when eligibility is changed.

We have a plan called “Across the Board.” When eligibility is set to the "A" union, the new increment salary shows in the Comp Ratio column (User Defined Column - Numer Column), and the increase amount is added to the Current Salary. After changing the eligibility profile to the "C" or "B" unions, the new increment salary still calculates in the Comp Ratio(User Defined Column - Numer Column) column, but the increase is not added to the Current Salary.
