Call logs showing on 2 iPhones

I have had 2 iPhones (work and personal) since 2007. I have used same Apple ID on both and never shared call logs. I upgraded to the 15Pro and ever since the call logs are appearing on both devices. Called Apple Support they have me turn off Handoff, Calls on other devices, sign out of iCloud, turn off iCloud Drive, iCloud contacts, iCloud Phone with no solution (multiple times).

if I have 2 diff phones numbers what is the purpose of sharing a log if I can’t tell with one is the one with a missed call??? This is very frustrating, has never happened before no matter what you turn off / on they keep showing.

@AppleSupport HELP PLEASE!
