Thanks for reaching out with this. It's an issue in the code of JFBConnect. We have that scope hard-coded in the Google authentication process and we shouldn't :/
We're working on a code change for it now. The new Autotune Network Settings tool is being updated with the birthday scope as well so that authenticating with Google should only ask for the birthday permission if you're actually importing that field.
If you can provide us with FTP access to your site, we can implement the changes directly once we have them. Otherwise, we can post the code updates required. It's not extensive.
To Private Message FTP credentials, please use the mail icon under my name to the left. We should have something ready very soon.
Thanks,
Alex
