Hello all,

I have a page type which has two different many_many's. Both of them have the $belong_many_many back to the page type. I display both of them as checkboxsetfields on different tabs. The first one works as expected, where the second one will save to the database and show on the front end but the checkboxes do not stay as checked so on the next save it removes all checked items. Some items that might be important: This is a multilingual site and the images are set on the English side and pulled through so as to only upload the images one time. I have included the code below and any help is greatly appreciated.

/* DataSheetPage */

<?php
class DataSheetPage extends Page {
	/**/
	private static $description = "Data Sheet Style Page";
	/**/
	private static $db = array(
	);
	/**/
	private static $many_many = array(
		'ApplicationImages' => 'ApplicationImage',
		'SpecificationImages' => 'SpecificationImage'
	);
...
	/**/
	public function getCMSFields() {
		$fields = parent::getCMSFields();

		//TABS
		$fields->findOrMakeTab("Root.RAImages", "Recommended Applications");
		$fields->findOrMakeTab("Root.SpecImages", "Specification Images");

/* This is the one working */

		//APPLICATION IMAGES
		$config = SiteConfig::get()->filter(array("Locale"=>"en_US"))->First();
		$ApplicationImages = ApplicationImage::get()->filter(array('SiteConfigID'=>$config->ID));
		$appImageMap = $ApplicationImages->map('ID', 'ApplicationTitle_'.$this->Locale);
		$fields->addFieldToTab('Root.RAImages', new CheckboxsetField('ApplicationImages', 'Application Images', $appImageMap));

/* This one is not functioning properly */

		//SPECIFICATION IMAGES
		$config = SiteConfig::get()->filter(array("Locale"=>"en_US"))->First();
