Matrix visual didn't filter - when Leave Codes selected. Guidance required

Hi All,

I have a sample pbi file. The Data model looks like this.

https://github.com/suvechha/samplepbi/blob/main/sample.pbix

I need to filter with Leave Codes. But my Matrix visual is not working with Leave Codes selection.

Please guide me, what I am doing wrong. 

The Filter is working with raw data.

But my matrix didn't filter.
