Remove Unwanted rows from Matrix visual

I'm trying to display certain hierarchy in the matrix like : in matrix row field we have style(table a) followed by material code(table b) followed by purchase order((table b) followed by document number(table c) and in the value field we have table a's qty column, table b's qty column, table c's qty column. What is happening right now is, it is showing all of the material code under style irrespective of the value available in Table b quantity and Table c quantity. what I want is to show the rows with the values available in table a,b,and c's quantity column. and also if I apply filter value is not blank from filter pane on table b's qty and table c's qty, it shows visual has exceeded available resources. Kindly help me out in achieve the desired result, that is no such rows which don't have value in table b's qty and table c's qty.
attaching expanded matrix visual in excel for your reference.The rows highlighted in red shouldn't be there in the matrix itself
