Role and User permission manager for Frappe CRM

Hi All,
In the frappe CRM when i set the user permission manager for the particular user its not getting restricted.

For Eg:

  1. In the lead I have set the permission for the user to access only the lead which is assigned to him. But when i login to that particular user the unassigned tasks is also listed in his login. I need to restrict that.

  2. Also when I set the role and user permission for the particular user its not restricted in the portal page CRM. All leads are viewing in the all logins.

Can some one help me on this please.

Thanks
