acfe_bidirectional_relationship breaks get_posts by meta value

Had to do this

<?php

add_filter(
	'acf/update_value',
	static function ( $value, $post_id, $field ) {
		if ( 'post_object' !== $field['type'] || 0 !== $field['multiple'] ) {
			return $value;
		}

		if ( is_array( $value ) || 1 === count( $value ) ) {
			return current( $value );
		}

		return $value;
	},
	10,
	3
);

Because srv/wp-content/plugins/acf-extended/includes/fields-settings/bidirectional.php:520 in acfe_bidirectional_relationship stores the bidirectional value as an array.
Even when no multiple values are allowed.

This leads to a serialized value for meta_value in the database.

Due to the serialized value get_post('meta_key=foo&meta_key=345') can’t find a thing. This is what your plugin breaks – hoping for a fix soon.
