TrafficEstimatorService Criteria overide in request

[sam...@wmarketing.ca]

I'm using the TrafficEstimatorService to fetch some stats on keywords for eventual campaign and custom reporting and during my testing i noticed that when setting up my request my language criteria will overide my location criteria if both are specified.

I can add location without language and the request will go through but if i specify both then only the language parameter will be taken in account by the request.

My code is very alike what is available in the google documentation so i don't understand why would my first criteria be replaced by the second one.

Thanks for any help. I hope my question is formulated properly

Here is a bit of my code where criteria are set, I'm using the PHP Adwords API client library v201705.

$campaignEstimateRequests = [];

        $campaignEstimateRequest = new \Google\AdsApi\AdWords\v201705\o\CampaignEstimateRequest();

        $campaignEstimateRequest->setAdGroupEstimateRequests($adGroupArray);

        

        $loc = new \Google\AdsApi\AdWords\v201705\cm\Location();

        $loc->setId($location);

        $campaignEstimateRequest->setCriteria([$loc]);    

        

        

        $lang = new \Google\AdsApi\AdWords\v201705\cm\Language();

        $lang->setId($language);

        $campaignEstimateRequest->setCriteria([$lang]);

        

        $crit = new \Google\AdsApi\AdWords\v201705\cm\NetworkSetting();

        $crit->setTargetGoogleSearch(true);

        $crit->setTargetContentNetwork(false);

        $crit->setTargetPartnerSearchNetwork(false);

        $crit->setTargetSearchNetwork(false);

        $campaignEstimateRequest->setNetworkSetting($crit);

        $campaignEstimateRequests[] = $campaignEstimateRequest;

        return $campaignEstimateRequests;
