New Clinic Address did not update for future appts

Hello, I have updated the address to a clinic in SI. I clicked “SAVE CHANGES”. The new address did not update for all of the future appointments at this clinic. It changed some of them, but not all. Can you tell me how to fix this? Also, if an appt from the past gets cloned to create a new appt, will the new address appear or will it keep the address from the cloned appt? Thank you!
