View complete AttestationHistory in the web portal

We would like to make the attestation history visible for certain user groups in the web portal. The view permissions for the AttestationHistory table have been fully assigned and there are no conditions for the display.
Under these conditions, all attestations that are present in the history should be visible, but only the attestations that the logged-in user have made himself are displayed.
We have tried to release all view permissions for all tables that have something to do with attestation and all authorization groups that have access to AttestationHistory have not set any view-conditions. Nevertheless, the display remains restricted.

We are working with version 9.2

Has anyone else had this problem or does anyone have an idea what the cause could be.


EDIT: Does anyone use the AttestationHistory and do you see the full history or just your own attestations? I would like to know if it is due to our settings or if it is a bug.
