ALLSELECTED and SLICER failure

Hi everybody! I got an issue I'm really struggling with.

Let's say I got an ID table, a Calendar table and a Fact table.

My fact table has "Id, Date, Yes/No" where the last one is a dicotomic variable.

My visual object composed by a date slicer, a GroupID slicer and the following table

And so on. 

I calculated the No. of Null Dates like this:

CALCULATE(DISTINCTCOUNTNOBLANK(Calendar[Data]) - SUM([Date Yes]) - SUM([Date No]), ALLSELECTED(Calendar[Data]))

The problem is that the GROUP ID slicer doesn't work properly.

When I select, for instance, a group which includes ID's 4 and 5 here's the outcome:

How can I work it out?

Thanks!
