I have searched the box and I do not have any other correlation engines running. Has anyone else ran into this issue or know how to correct it?
Hmm, if you do not already have added a Correlation Engine to your receiver I would suggest you contact support.
But before that click on "Receiver Properties -> Data Source -> Write" button and then try again to add your Correlation Engine.
Change your Device view to Device Type.
If it's there you already defined it.
you can edit it to a more appropriate name there, and also enable disable and remove it as needed.
