[2.0.0-RC13] TransitiveMemberOfRequestBuilder ignoring QueryParameters select

Upon creating a TransitiveMemberOfRequestBuilder and applying a TransitiveMemberOfRequestBuilderGetRequestConfiguration->queryParameters->select I can see the URL is changed to include the $select fields in odataNextLink. But when I actualy run the query with get($groupsRequestConfig) the additional fields are not returned.

If I take the URL and put it into graph explorer, it returns the fields as requested.

Sample code and var_dump's

<?php

$groupsRequest = $GraphServiceClient->me()->transitiveMemberOf();

$groupsRequestConfig = new TransitiveMemberOfRequestBuilderGetRequestConfiguration();
$groupsRequestConfig->queryParameters = new TransitiveMemberOfRequestBuilderGetQueryParameters();
$groupsRequestConfig->queryParameters->select = [
    'id',
    'samAccountName',
    'displayName',
    'groupTypes',
    'securityEnabled'
];

$groupsResponse = $groupsRequest->get($groupsRequestConfig);    # Http\Promise\FulfilledPromise
$groups = $groupsResponse->wait();  # Microsoft\Graph\Generated\Models\DirectoryObjectCollectionResponse

$myGroups = []
foreach ($groups->getValue() as $g) {
    $myGroups[] = $g->getDisplayName();
}

PS. Please create more documentation, this sdk is a monster for having so little documentation and examples.

Start at TransitiveMemberOfRequestBuilder->get() and its queryParameters->select handling, then trace how the response populates DirectoryObjectCollectionResponse and Group models. Compare the requested fields in the generated URL with the fields available after wait(); done means the selected properties are returned consistently.
