Subscripion report is not synced with the synced slicer but PowerBI app shows is correct

Dear,

I created a report with on the first page a dropdown to select the week of the year we are in, with an overview of the worked hours in a specific week. On that first page I see all the technicians.

Then I created a second page with only data of a specific technician. So I set a filter on that page with only that technicians data being available.

I like to create this for all of the technicians in the company.

I have a premium account so I can share it with them trough a subscription.

In the PowerBI app all works fine. when I select week 48, I see week 48 on the second page too.

But on that second page there is a subscription running and there it goes wrong. 

The email we receive is never the correct week.

So nothing wrong in the report but in the subscription email and I don't know how to change this.
