help on hiding months with no allocated values in a matrix

[Islam]

Hello Everyone

i'm trying to create a matrix showing the Pouring Amount which represents Revenue and Total Expenses which is the sum of Expenses and Purchased materials 

so i created the following measures

Total Materials Amount:=SUMX('Total Amounts','Total Amounts'[Materials Amount])

Total Expenses Amount:=SUMX('Total Amounts','Total Amounts'[Expenses Amount])

Total Pouring Amount:=SUMX('Total Amounts','Total Amounts'[Pouring Amount])

Net Profit/Loss:=[Total Pouring Amount]-[Total Expenses]

and that's how i wanna show the pivot table

i have no values for January 2020 but there are values for January 2021 so when i filter to show just January 2021 (It's Called يناير) with years rows displayed i get the correct values for January 2021 but an empty month for 2020 with the sum of all 2020 values like following picture

I want to hide 2020 January with no values and also fix the grand total calculation

Any help would be highly appreciated

Change

Net Profit/Loss:=[Total Pouring Amount]-[Total Expenses]

to account for situations where ISBLANK([Total Pouring Amount]) is true.
