Flush nested form field cache

For a strange reason the field of nested form are cached.
Currently the plugin does not export latest fields added

I’ve found the lines involving this problem inside nestedFormField.php

// Cache the results.
		$this->fields = array_reduce( $nested_form['fields'], function ( array $fields, \GF_Field $field ) {
			if ( in_array( $field->id, $this->field->gpnfFields ?? [], false ) ) {
				$fields[ $field->id ] = $this->transformer->transform( $field );
			}

			return $fields;
		}, [] );

Disabling the if it is working

if ( in_array( $field->id, $this->field->gpnfFields ?? [], false ) ) {

Have you got a solution to refresh the field of nested form from dashboard ?
