I’m the Referring Party, and I made a mistake during referral creation and want to edit details so that the Contract reflects the correct information. How can I edit it?

Unfortunately, you have the cancel the referral to edit the referral information. After doing so, a re-assign button will appear on the top right of the referral details page, which will re-create the referral automatically (no need to re-input the referral details again), and you can award it again to the same Receiving Party.
