It's difficult for me to tell what you're asking about.
For each import/export operation you're asking about (both successes and
failures), could you give the following information clearly:
* Are you exporting secret keys?
or exporting public keys?
* where were the secret keys originally created? (on what program does
the original export happen?)
* which program is doing the import?
* does the program doing the import modify the OpenPGP certificate in
* does it re-export the OpenPGP certificate? if so, is that
re-exported certificate loaded back into the original program?

it is not normal for the primary key to be marked as
authentication-capable ("A"). If you have a tool that is doing that,
please report back what tool that is, on what platform and what version!
