Left navigation keeps bringing back to the master version

To reproduce:
1. Go to the docs: http://googlecloudplatform.github.io/gcloud-node/#/docs/v0.14.0
2. Make note that you're looking at version 0.14.0
3. Click anything in the top section in the left nav bar (ie, PubSub)
4. Make note that you're now in the master branch version of the docs... (at least according to the URL)

Any ideas how we can avoid dropping into the master version?
