No, if you have a keyring with a duplicate key, the merge happens on
import.  Since the keys are already there, the way to fix it is:

* export both keys to a file
* delete the keys on the keyring.
* import the keys again.  They will be merged.

Make a backup first, just in case.

You have more than one subkey.  Many keyservers do not accept keys
with multiple subkeys.  Try using hkp://subkeys.pgp.net as your
keyserver.
