Why does my measure not work when I use ALL(Calendar), it still filters values when I choose a month

[ale_BI]

The measure is the following, and it needs to calculate the total sum for the year, regardless of what month is chosen. But it keeps filtering anyways

YTD Revenues TOTAL = 

CALCULATE(
    SUM('FACT MCR'[amount_mgmt]), 
    ALL('Anag. Calendar'),
    'Anag. Account (mgmt)'[class_i]="Rev",
    'Anag. Company'[cod_company]<>950,
    'Anag. Calendar'[month_name] = "December")

hi @ale_BI 

pls check:

1) is the sliced column from the Calendar table?

2) are the tables connected with Calendar table?

[ale_BI]

Hey, thanks for the response. No it's not, and the tables are connected together, yes
