Multiselect Works the first time, then reverts to regular select box

I am using Select2 loaded through a CDN. The first time, it works, but then it reverts to a regular select box (losing the Select2 dropdown). We are on WordPress and using the Toolset plugin to create the options.
Here is the external .js:



$(document).ready(function() {

I have also tried just ‘select’ instead of the class name ‘.js-wpv-filter-trigger’ and it behaved the same way.
The two screenshots show the console on load (when Select2 is working) and after the first selection (When it is not loading).

This issue is resolved. I was using toolset and here is the fix:
( function( $ ) {
$( document ).on( ‘ready js_event_wpv_pagination_completed js_event_wpv_parametric_search_form_updated js_event_wpv_parametric_search_results_updated’, function( event, data ) {
})( jQuery );
