Dear community ! 

I'm using Qlik Sense on windows May 2024, I try to use window function in script.

But I noticed that when adding a window function in my table all null values of the table are transformed as "-". 

You'll found attached a small exemple. 

Is that normal or already reported as bug ?

Is there a workaround in order to keep null values as null ? 

Regards,

Pauline
