Error: An item with the same key has already been added

When clicking into the Online Express plugin after enabling Consent Tracking, users notice that Online Express will automatically attempt to add opt-out Consent records into the Raiser's Edge database and then generate the error "An item with the same key has already been added".
This was resolved in the 5/1/2018 update of Online Express. If you are still experiencing this error after 5/1/2018, please contact Support.
