Not sure, maybe someone else can help with answering that.  But the
method of extension of sub keys is simply to add another self-signature
to them, with what I assume is an expiration date on the signature.  I
don't think the key itself expires, but the self signature on it does.
This would explain why if your top key expires, all the sub keys expire
as well.  Try to re-sign the sub key.

And please someone correct me if I am wrong here.
