docusign checkbox value based on API call not working - checkbox

Question

I am trying to pass selected checkbox values from a real estate contract via the REST API. Currently I am able to make the check boxes show up on the document but they do not show checked or uncheck based on the True/False data passed. What am I doing wrong? I've tried setting them as read only and mandatory on the template and they still don't populate the checks in the boxes.
*updated with correct code below
$sellerTabs = new \DocuSign\eSign\Model\Tabs();
$count_fields = 0;
foreach ($fields_data as $key => $field_value) {
//echo $field_value."\n";
$seller_address[$count_fields] = new
\DocuSign\eSign\Model\Text(["tab_label" => $key,
"value" => $field_value]);
$count_fields++;
}
$tab_group = $_REQUEST["group"];
$sellerTabs = new \DocuSign\eSign\Model\Tabs();
$count_checks = 0;
foreach ($checks_data as $key => $check_value) {
//echo $check_value."\n";
$seller_checks[$count_checks]= new
DocuSign\eSign\Model\Checkbox(["tab_label" => $key,
"selected" =>
$check_value,"Checkbox_Group"=>$tab_group]);
$count_checks++;
}
//file_put_contents("create_event.log",
"json_decode($checks, true);" ,FILE_APPEND;
"json_decode($fields, true);", FILE_APPEND);
//exit();
$sellerTabs->setTextTabs($seller_address);
$sellerTabs->setCheckboxTabs($seller_checks);
$envelop_definition = new
DocuSign\eSign\Model\EnvelopeDefinition();
$b_roles = array();
//exit();
// echo $roles_data;
foreach ($roles_data as $role_data) {
// echo $role_data;
$data = explode("|", $role_data);
$role_data = new DocuSign\eSign\Model\TemplateRole();
$role_data->setName($data[0]);
$role_data->setEmail($data[1]);
$role_data->setRoleName($data[2]);
$role_data->setRoutingOrder($data[3]);
$role_data->setTabs($sellerTabs);
//echo $role_data;
array_push($b_roles, $role_data);
}
//var_dump($b_roles);
/*echo "<pre>";
print_r($_REQUEST["templateID"]);
exit();*/
// $envelop_definition-

$templateRole3/));
