Count of Weeks based on Date filter

[PKPK90]

Hi, I am trying to create a measure to show number of Weeks from Calendar table based on slicer date filter.
This is what I have done so far

CountWeeks = CALCULATE( DISTINCTCOUNT('Calendar'[YearWeek]), FILTER(VALUES('Calendar'), 'Calendar'[Date]>=[Minimum date] && 'Calendar'[Date]<=[Maximum date]))

it is working fine in visuals like card or as a single value, but when I am using it in table with columns it is always showing 1, so it is counting per column row, I would like to get the same value(91) regardless of additional variables.

Slicer for 'Calendar'[Date]:

Card visual: 

Connection:

MaterialTransactions is my table with all data needed

Calendar is my calendar table, also connected with different tables.

Expected result:

[PKPK90]

Thank you for your input, but still I am receiving "1" per row.
