Hello Constantin,
Not knowing your configuration I can only suggest to check the Admin guide for:
- dir.corp.viewPersistence
If 0, the corporate directory search filters and browsing position are reset each time the user accesses the corporate directory.
If 1, the search filters and browsing position from the previous session are displayed each time the user accesses the corporate directory
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
