Export only one question of a dashboard


My teammate created a dashboard with 5 questions inside.
Then she created an alert on the dashboard to receive only the result of one question.

When she receives the mail the five questions are present in the mail.
Below the capture of the configured alert:

Below the mail received:

Any idea why we receive all questions and how can I receive only one ?

Many thanks

If the question has more than 10 rows in the result you’ll receive the attachment


I am not sure to understand...
In the configuration I checked only one question but the five are present in the mail. Is that normal ?
If i understand well, despite the configuration if questions of my dashboard have more than 2000 rows I will always have them in the mail even if I did not checked them ?

How can I have only one question in the mail ?
