Week appears in two months when drilling down. Is there a way to change that?

[afaro]

When I am drilling down from month to week, my calendar is such that week appears in two months. So, I have two calculations for the same week. The value for that week is the sum of the two calculations. Is there anything that can be done to show the entire week once only as the sum of the two values in my visuals?

Only if you remove the month from your field hierarchy.  Weeks are incompatible with months, quarters, and years.

Or use one of the many arbitrary "weeks in month"  approaches.
