Making changes to contact information within the Contact phase, will not populate in a newly generated contract. If an installer needs to make changes to the homeowner's address or contact info once they've reached the contract phase, they would have to navigate to the qualification phase and select Review Name & Address Information. This will display the address and contact info for the applicant(s).
From this point, the user can select Edit or +Add to make changes that will reflect in the new or revised contract.
