do you see the same error messages when you use the more modern --quick
command-line syntax?

    fpr=$(gpg --with-colons --quick-gen-key "Test user <test at example.org>" ed25519 | awk -F: '/^fpr:/{ print $10 }')
    gpg --quick-add-key $fpr cv25519

what version of gpg are you running when you see those warnings?

     --dkg
