Echo Devices not showing up


I am trying to setup Echo Speak and went through all the steps but none of my 4 Echo devices are showing up in WebCoRE when I look at “Available Devices”. Most all my other sensors show but none of my Echo’s. I have enabled the ST skill on Alexa. There is a “SmartApp” called Amazon Alexa. When I go into webCoRE, Settings, Available Devices, Available Devices, Capability group 2 (or any of them), Music Player it is grayed out saying “You can’t currently add this”. I am new at this and just getting started. Any help would be greatly appreciated. I searched the forums, a few users having similar problems but their resolutions dont seem to be fixes for my issue.
