@sododesign I tested your function and I found an error.

if ( ! function_exists( 'acf_wp_kses_post' ) ) :

	function acf_wp_kses_post($data, $post_id=0, $field=array()) {
	
		if (isset($field['type']) && ($field['type'] == 'repeater' || $field['type'] == 'flexible_content')) {
			// no need to run it on repeaters
			// will be called again for each subfield
			return $value;
		}

		if (!is_array($data)) {
			return wp_kses_post($data);
		}

		$return = array();
		if (count($data)) {
			foreach ($data as $index => $value) {
				$return[$index] = acf_wp_kses_post($value);
			}
		}

		return $return;
		
	}
	
endif;

add_filter('acf/update_value', 'acf_wp_kses_post', 10, 3);

I use repeater fields at option pages. If I use this function, after clicking the update button, all values are lost and not saved.

What is the reason for this issue?
