DAX Query for Running Total

Hi,

I created a simple view of 3 columns, (city name, date of completion for that city, a flag as 1 for filtering cities with completion date) like below

now i created a measure (like a new column) to find a running total of completed cities as date move forward like below: (expected column for running total)

I wrote a below Measure and surprisingly its working on my personal machine, but not working on my work machine.

Measure = CALCULATE(SUM(MYVIEW[FLAG]), FILTER(ALL(MYVIEW[COMPLETIONDATE]),MYVIEW[COMPLETIONDATE]<= MAX(MYVIEW[COMPLETIONDATE])))

Instead I get below reponse : 

what am i doing wrong, as i said, same query is working fine on my personal laptop
