Creating relationship between Total Spend table and Concession Table

Hi everyone, 
I'm stuck on a report that has 2 tables. First is concession including Supplier name, Product group, date, claim amount, supplier agreed to credit. Second is Total Spend with Supplier name, Product group, date and total spend in USD. I need to make a column chart that works with filter by Product Group and Supplier name. 
Here is the model that I build but it doesn't work with both filters. I created 2 table Group and Supplier with distinct Group name and Supplier name and make those table as a brigde to Total spend table. 

Here is the Concession table 

Thanks in advance
