1.423 is not a valid GnuPG version, so i assume you meant GnuPG 1.4.23.

the "classic" version of GnuPG (the 1.4.x series) not only does not
support merging secret keys effectively, it does not support modern
asymmetric cryptographic mechanisms like curve25519 and ed25519.

If you upgrade to the modern version of GnuPG on your windows machine,
and then try to re-import, i think you'll find the merge issue resolved.

You'll also get better support going forward.
