Why is Count and Distinctcount together with Calculate giving a negative number?

[pbi95]

I'm writing some formulas that use the Count or Distinctcountnoblank functions, but when I combine them with Calculate to filter based on a condition in the data, it returns a negative number for some of the measures but not all. Whether it's positive or negative seems to vary with the condition applied. See below for an example where I'm trying to output the count of call_id whose call type is "123". How is it even possible for this to return a negative number? How do I make it work properly without having to do a series of IF/THEN clauses?

Measure Example =

CALCULATE(DISTINCTCOUNTNOBLANK(table[call_id]), table[type]="123")

Hi @pbi95 

Could you please provide more raw data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples? It would be helpful to find out the solution. You can refer the following links to share the required info:

Ok for me your measure is ok. so I do not understand why you have negative results

Hello,

PLease give us some data samples

The call_id values are just random numbers from 5 to 7 characters in length serving as an identifier column. It shouldn't affect the results of Count and Countdistinctnoblank. The output I'm getting from the measure example is -24.
