When selecting the action Send Email Campaign Message for an engagement plan in design phase, the dialog box opened up, contains all Email Campaign managers for all sites, but does not include emails created under it. It only shows redirects in email campaign manager. Not sure why this is not working in Sitecore 8.1

How do i set the data i see here? The Engagement Automation Action: Send Email Campaign message has a Editor Url that gets its, dialog with options the value is as shown below http://sitecore/shell/default.aspx?xmlcontrol=EmailCampaign.SelectStandardMessage

I was not able to find the control . Dont know how to solve this. Not able to send any emails as an engagement action.
