PGPPublicKeyRing from Bouncy Castle package

[Sucharitha.X.Panthika at chase.com]

I am creating keys using gnupg command line and accessing the keys for my application using Bouncy Castle PGPPUblicKeyRing object reading the pubring.gpg file under user home directory. I have three different public keys one for app and one for web and one for local testing. When debug the PGPPublicKeyRing using Iterator I see only two keys in list and only one of them has uid associated.  Where all my three keys have different uid's. 

Anyone knows why I am not getting three keys with all uids

thanks much
