Dear Sir
Thanks with your response.
Yes, the original format was <street name> <street number> <floor>. Many records were stored in the phone as <floor><street number> <street name>, and later resynced in this altered format.
I happened when I create the Google Account in Iphone XR with IOS 13.6. I had the same situation with an old Iphone time ago.
I couldnt see the same with new cotacts in Iphone.
And it is not the only error. If I edit any contact, and add a bithdate without year, It is not recorded.
Another bug, is that I can add, alter, or remove the Note field without editing the contact, and there is no choice to discard the changes.
If I remove the Apple Contacts App, How can I get it again?
Sincerely
Alfred
