Volunteers Wizard Clone Existing Campaign Error

I am trying to clone an existing volunteer campaign using the Volunteers Wizard and I am receiving the following error message: "Error: duplicate field selected: GW_Volunteers__Campaign__c" 

When I try again I receive another error message: "Error: cannot specify Id in an insert call".

Previous threads have mentioned it is an object permission issue. I've given my profile permissions to all fields in the relevant object (Campaigns, Volunteer Jobs, Volunteer Shifts, Volunteer Hours, etc.), yet I am still getting the error. 

Does anybody have recommendations on how to solve this issue?
