Matrix including more entries from Rows which it should not as per filters applied

Hi,

I am currently using the Matrix Visualization, on there I have a field called Customer in the Rows section and one field called Available Days in Values. 

In my Filter Pane I have the following fields with the values in Bold that I have applied the filter to the Page:

Year

2020

Month

Jun

Day

25

Person Name

John Smith

This will show the correct Customers in the Matrix Visualization, but when I add a new field called SLA % to the Values  section the Customers increase and is showing Customers where John Smith has not made any Visits for that day? How do I just only show the Customers as per before I added the SLA % measurement, below is the DAX formulas for each Values:

Rows

Customer

Columns

Thanks
