Date Slicer NOT filtering correctly ?

Sample Workbook Sample Workbook  

I posted a link to the example .. it's tiny

below are the 2 datasets (also tiny) just for example
dim_client

fact table

The data is super clean .. no blanks ect, so I know that's not the issue

It really comes down to the GROUP Calculated Column IS NOT respecting the YEAR slicer.
it does work fine for the other 2 slicers though (customer name and state) ?

dim_client table
client_id,client_name,state
1,Client A,IL
2,Client B,CA
3,Client C,OH
4,Client D,CA

fact table
client_id,job_id,date,rev,hours,type
