Error on original lease

[Molly Murphy]

I went to do a lease renewal on one of my SFR properties and I realized the original lease had an error in the dates. It indicated the lease went from Feb 8, 2019 to Jan 31, 2019 instead of Jan 31, 2020. Neither me nor the tenants caught this error previous to today when I opened the document. I'm assuming I should correct and amend the original lease first and then do a simple renewal form? How do I go about correcting the lease (haven't made this kind of mistake before)?

Thank you!
