cannot import contact.abbu file?

I have a macbook pro on monterey, and just got a new mac pro on 15.3.1 I opened Contacts on my macbook pro, and exported "Contacts archive", copied the file to my mac pro.. opened contacts, did "import", selected the .abbu file.. a dialog window opens asking am I sure I want to replace my contacts data, I click "Replace All", the modal closes, and NO CONTACTS HAVE BEEN IMPORTED... The abbu file is 14mb.
