Hi!

I would like to know if anyone can help me hidding the highlighted section in the image bellow.

I already tried to add the reports that appear on that navigation bar to a specific collection report and they still appear. Also, I've tried to set the visibilty and permissions to a specific role but it didn't help.

I have noticed that the reports that are appearing in the navigation bar are the reports in the report category named "Reports" (as showned in the second attachment).

Thank you!

You have to remove the report in the Report Collections by unchecking the show in Navigator box
After doing this you will need to Check in the changes for it to take effect
Hopefully this is what you are looking for
