[Plugin: NextGEN Gallery] using shortcode for different galleries on different pages

I have a salon website with a gallery page wherein the user must first select a stylist prior to viewing their individual gallery.

I planned on using NextGen to house the images in stylist specific galleries, and using the NextGen shortcodes on each stylists page.
However, this doesn’t seem to be working. For example, when viewing Rebecca’s page, the gallery doesn’t show despite having the shortcode in the WP Page content field.

Any ideas what could be causing the problem?

The only solution I can come up with is to create a different page template for each stylist and utilize the shortcode there, but surely there is a better route to take?

Pastebin- relevant code from gallery.php
