SecuritySuite - SuiteCRM and CE Teams

CRM: SuiteCRM 7.9.5 SecurityGroups: SuiteCRM_7.9.5_SecuritySuite_v3.1.2.zip If I try to add the "Group Messages"-Dashlet to the Homescreen, then a Smarty error will be displayed on selection popup:  As far as I can see this error leads to a missing module variable in modules/SecurityGroups/Dashlets/MessageDashlet/MessageDashlet.meta.php. Adding the dashlet is working, and it will be displayed without any problems on the Homescreens. But as soon as I want to do any further actions (edit tab, add tabs, add dashlets) on the homescreen the popup shows the loading image inside the popup forever and nothing happens.  As soon as I remove the "Group Messages"-Dashlet everything is working as expected. The second problem looks not as a related problem to the missing module variable. Could you please check if this is a general issue of the curent SecuritySuite module? Thanks, armin
