SecuritySuite - SuiteCRM and CE Teams

Hi, I have used this plugin for our Sugar CRM system version 6.5.20. Here i have tried creating two hierarchy roles that i.e "Owner only " and "Group only". I have made sales team 1 and allocated two users "A", "B" and "C" in this group. Here i have assigned owner only roles to "A" and " B" and Group only role to "C". The intention was to create the Sales team and manager hierarchy. I login into user accounts, in user accounts of "A" and "B" i see the only activities which their owners are creating i.e "A" and "B" itself. In activity stream also it works fine. But when i login through "C" account i get the privelege of watching the leads/opportunities on which "A" and "B" are working along with my person activities as am user "C". But when i try to see activities in "Activity stream " i dont get able to see teh activities of user "A" and "B". Please provide your response over this.
