Saved passwords missing after migration from old to new Mac with Sonoma 14.7

i recently used migration assistant to transfer from my old macbook pro to my new one with Sonoma 14.7, but none of my saved passwords made it to the new computer; did i do something wrong?

i have had to re-enter all my previously saved passwords, and those are now the only ones in the password file.
