Why doesn't my visual drill down when I filter ?

Hi Community!

Here's my problem, I am doing a simulation financial reporting and I dont understand why my visual doesn't drill down when I filter the client. 

Here is the situation, on the top left, a tiler by Customer, SubCustomer, Mold (of the article) and article. 

On the top Right, the simulation parameters. 

On the bottom left, a view of the actual costs of each customer and on the left the same visual but taking into account the simulation parameters. 

I don't get why when I filter with the customer, I get this :

While when I fitler with subcustomer, mold or article I get the same vizualisation for both of the visuals (which are good). Thus, the problem only occur for the first filter step (customer)

I would like to obtain the same display as the left one for the right one. 

Could the problem be that the Actual Cost are referenced in columns in the data base, while the simulated costs are based on a measure? 

Can someone help me ? 

Thank a lot
