SharePoint - Duplicate Content Error

This was a strange problem! A user tried to activate the "SharePoint Server Publishing Infrastructure" feature and received an error saying "A duplicate content type named "Report" was found." In addition to this problem there were a couple of features that were enabled for testing that I was unable to disable.

The problem was fixed by disabling the two features circled below:

Once these two feature were deactivated the "SharePoint Server Publishing Infrastructure" feature could be activated.
