Pages always visible, even when user not having access

Hi there,

I think some things are not working correctly:
– a specific page setting: https://d.pr/CvSZtX
– settings of specific user: https://d.pr/VoSi0S
– plugin settings for pages: https://d.pr/FH5XYt

All pages are visible for this user. Even pages when they not have checked his access rights.

Am I doing something wrong?
Thanks in advance.
Justin
