So gpg asks the agent for your secret primary key (69F91A22) but the 
agent cannot provide it. Then it asks for the secret subkey and gets it.

Next questions:

* What exact version of GnuPG are you using? It looks like you are using 
a version from the 2.1 branch, not 2.0. Please give the output of `gpg2 
--version`.

* Can you *use* your secret primary key? Try performing any action 
requiring the secret primary key (such as signing a message, assuming 
you do not have a signing subkey).

* If you can reproduce the issue at will, can you try exporting the 
private keys again, but with logging of debug informations?

Add the following lines to your ~/.gnupg/gpg-agent.conf file (create 
that file if it does not already exist):

   log-file /wherever/you/want.log
   debug 1024

Reload the agent (gpgconf --reload gpg-agent) and try exporting again.

It's starting to look like a communication problem between gpg and the 
agent. What problem exactly, I have no clue.
