I looked at one of your posts, and I passed it through Facebook’s debug tool:
https://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fbellastindahan.com%2Fwhole-natural-foods-that-clear-acne-fast%2F
As you can see, there are errors there. These errors are preventing Publicize from working as expected. You have these errors because something (likely your theme) is outputting og meta tags (that Facebook requires) on your site; the problem lies in the fact that Jetpack also outputs those tags, so you now have duplicate tags, which Facebook doesn’t like. Have a look in your theme files (maybe in header.php) for whatever is outputting those tags, or ask the theme author for assistance:

Alternatively, you can turn off Jetpack’s tags, but they are more complete than your theme’s tags, so I wouldn’t necessarily reccommend this. You can turn them off by adding this line to your theme’s functions.php file, or to a Functionality plugin:
add_filter( 'jetpack_enable_open_graph', '__return_false' );
