Micro-certification Performance analytics

Hello everyone, I have a sticking point on the Performance analytics micro-certification simulator. I filled it to 80% and I have 20% left, here are the blocking points. Can someone please help me?

Look :

 Modify and Share the Incident Management Dashboard - Failed

1. Set the Incident Management dashboard owner to Beth Anglin. 
2. Click into the Open incidents widget on the Incident Overview tab to open the Analytics Hub.
3. Create a new global target at 180 with a start date of approximately 3 months ago. 
4. Return to the dashboard and modify the Open incidents widget as follows:
   
   • Enable Show target in the Display Settings section.
5. Verify that the dashboard displays the new Target as shown

Configure Widget Filtering

As you can see, the dashboard filters you added in the previous step do not seem to work. Perform the necessary configuration on the Number of Open Changes widget on the Change Overview tab as follows:

• Enable this widget to follow the dashboard filter.
• Configure the widget to display separate trends for multiple elements.

Thank you
