Calculated measure changes value when matrix is converted to graph

Hello, 

I have two matrixes (see below), both tables have same filters but when I select only the percentage column the value changes. Can someone explain why this is happening?

Matrix 1

PPE         Hours    Sched Hrs    %

2/9/19    23,431   109,120        21.47%

Matrix 2

PPE           %

2/9/19    5.42%
