Question - Support-Access Lists

I´ve tried to config a group named “Compliance Gruppe” in Eramba for reviews. The group should only see items that are related to it. But testing it I´ve seen more items for example at the tab Asset Identificiation. I see only a relation between the group and the first two assets. I don´t understand why I see the other items. I already looked at the item report to see all the relations in the system but still not get it. Could you please help me to understand this?
