Previous Quarter measure shows values which don't exist

[MCacc]

Hello, 

I'm trying to write a measure which shows my values in the previous quarter compared with the date I select from my slicer.

The date in my slicer comes from a Calendar and it is in a relationship with my fact table in a 1:N relationship through the Date field. 

In my date field I have onyl two values:

30/09/2023

30/06/2023

In the visual I have two measure, a simple count of a field, and the previous quarter measure of that count. 

The latter works fine when I select 30/09/2023 and it correctly shows the values for the 30/06/2023. However, when I select 30/06/2023 instead of blank values (since I don't have 31/03/2023 in my datafield) the measure shows again the values for 30/06/2023. 

Any clue why this happens? 

Thank you
