Active assignment request

We are facing the same issue 8.0.2 IT shop assignment is not working as expected basically it show for the requester that the product he requested is assigned   (E.x business roles/ other entitlement) user try to use requested product since approvals got granted and it show as assigned in ITshop 

however in manager the requested product is not assigned yet and all users who face this issue will have an overview box called 'Active assignment request'
