Tiled gallery not displaying options

Running WP version 3.7, recently installed jetpack just for the purpose of using the tiled gallery. However, I am not given any options for display (rectangular, circle, square), it just shows up in the square version. I really want the rectangular version, this is driving me nuts. Any help would be really appreciated!

I don’t have much experience with WP sites, so thanks for any feedback.
