In Manage Jenkins - Manage Credentials page, we have added one Apple Developer Profile and successfully able to use it to sign builds. Anew project is now hosted on this jenkins instance that requires a different profile. I went to Manage Jenkins - Manage Credentials page, and added a second Apple Developer Profile (with a different description). Upon uploading the second developer profile, I now see that the first one says "There's no certificate in this profile". If I re-upload the first developer profile, I now get the same "There's no certificate in this profile" error on the second developer profile.

When I examine the HTML on the page, I notice that the <input type=hidden name=id > tag has differing value's for the two trees (to be expected), so I'm not quite sure why we're losing the contents of the previous profile when uploading a new one, unless it's because for some reason only one is supported.
