Facebook profile issue after transferring data to new iPhone 16

I recently bought a new Iphone16, I saved all the stuff on my Iphone13 to the cloud.

When that information was transferred to my new phone my facebook page was a different one with my login name and number but very little info in it. My real page/profile showed up as a friend request. So far I have not been able to correct the error, I am looking for help , please.
