Line item filter on a dashboard

Dear all, 

I'm having trouble setting up some filters on my dashboard.

I published my line item "mover class ?" (which is a list) on my dashboard and i want to use it as a filter (by then creating a boolean line item.)

But when i select one choice on the list on my dashboard (here : best mover) it only applies to the first cell.  (cf screen)

Do you know how i can fix it ?

Many thanks in advance.
