PHPword fails to set value for template variable

[Kamala2017]

I am using template to export document , for one of the downloaded file the content is same as the template variables and blocks .It fails to set the values for that particular section. However there not any specific difference in text , i have also enabled special character escape.

My Template

Education
${educations}
• ${eduyear}, ${edumajor}, ${eduinstitute}.
${/educations}

Certification and Training
${certificates}
• ${ceryear}, ${cermajor}, ${cerinstitute}.
${/certificates}

Exported Document

Education
${educations}
• ${eduyear}, ${edumajor}, ${eduinstitute}.
${/educations}

Certification and Training
${certificates}
• ${ceryear}, ${cermajor}, ${cerinstitute}.
${/certificates}

Code for above section

$edulist = array();
foreach ($empEducationList as $key => $value) {
$eduService = new EducationService();
$eduDetails = $eduService->getEducationById($value->getEducationId());
$level = $eduDetails->getName();
$fromYear = ($value->getStartDate() != null and $value->getStartDate() != '')?date('Y',strtotime($value->getStartDate())):'';
$toYear = ($value->getEndDate() != null and $value->getEndDate() != '')?date('Y',strtotime($value->getEndDate())):'';

        $eduYear            = ($toYear > $fromYear)?$fromYear.'-'.$toYear: $toYear;
        $edulist[]          = array(
                                        'eduyear'               => $eduYear, 
                                        'edumajor'              => $level.' in '.$value->getMajor(),
                                        'eduinstitute'          => $value->getInstitute()
                                    );
    } 
    $templateProcessor->cloneBlock('educations', 0, true, false, $edulist);
