Hi,
I seem to be facing an issue with a user being unable to view the project in the Portal.

The user is a Customer, and not an agent, but there is no Project in his Portal, and the Permission Helper shows the below.
is not a member of any of these project roles: Service Desk Team, Administrators, atlassian-addons-project-access. You can change this by going to the 'JIRA1' project roles 
All permissions seem to be fine but I did not understand why its showing above to add thei customer to the mentioned roles.
User is added to Project Settings > People as well with Service Desk Customer Role.
