In JFBConnect 6.4, we changed the way that posts are made to Facebook Pages to always be 'from' the Page itself, not from a user account. That's how it worked on about 90% of sites already, but some sites were seeing the posts go to the "Posts to Page" area, like you describe. That isn't what most users want, since they're trying to push content to their feed.
If you want the posts to appear as from your user account and not directly in the Timeline, please edit the following file:
/components/com_jfbconnect/libraries/provider/facebook/channel/page.php
Around line 135, you'll see:
$params['access_token'] = $this->options->get('access_token');
//NOTE: Uncomment to use user access token instead of page access token
//$params['access_token'] = JFBCFactory::usermap()->getUserAccessToken($this->options->get('user_id'), 'facebook');
Uncomment that last line by removing the // from the front of it.
Test and let us know how that goes. We may add an option in a future release to select whether posts are from the Page itself or from the user account.
Thanks,
Alex
