PowerBi Report Security

[All41S]

Hello,

we're using PowerBi Report Server OnPremise (March 2018) and have different Reports in different folders.

At the settings i changed the security settings for the reports with AD Groups.

But today i registered that the permissons i setted up are not working.

Everybody see all folder and all reports.

Any Ideas what's wrong?

Best regards
