Meta Box

Uncaught Error: Syntax error, unrecognized expression: ##type_1:not(.rwmb-clone-template ##type_1)

I can't test it at this time as this is on a production site where these are being used constantly. Another thread with others experiencing the issue is here: https://support.metabox.io/topic/conditional-login-in-swich-on-1-30-1/

Not sure what I am missing here, the field is not updating.

<?php
add_action( 'rwmb_district_tax_rate_after_save_field', function ( $null, $field, $post_id, $old, $new ) {
    rwmb_set_meta( $post_id, 'district_proposed_rate', $new );
}, 10, 5 );

To expand on this issue, I added the Custom Post Type UI plugin and created a CPT and it appears in the query field. So the issue is isolated to MetaBox.
