Set send time

I have set the send time of the report settings on 0 hour(s) and 5 minutes.

Because I want to send a sales report e-mail every day at 0.05. But right noq I receive the report on very different times;

28.09.2020 – 2.34
27.09.2020 – 2.26
26.09.2020 – 9.06
25.09.2020 – 4.45
24.09.2020 – 2.05
23.09.2020 – 8.05
22.09.2020 – 6.01
21.09.2020 – 3.37
and so on.

The video is outdated and the documentation isn’t very helpfull either. I hope you can help me out! Thanks!
