Describe the bug and add attachments

Ive tried switching the renderers for pdf (domPdf, tcpdf, mpdf) but the result is the same

Ive tried to convert the saved docx to pdf but the result is still the same. This is the docx output

Expected behavior

This but in PDF

Steps to reproduce

        $phpWord->addTitleStyle(1, ['size' => 14, 'bold' => true], ['keepNext' => true, 'spaceBefore' => 240]);
        $phpWord->addTitleStyle(2, ['size' => 14, 'bold' => true], ['keepNext' => true, 'spaceBefore' => 240]);

        // 2D charts
        $section = $phpWord->addSection();
        $section->addTitle('2D charts', 1);
        $section = $phpWord->addSection(['colsNum' => 2, 'breakType' => 'continuous']);

        $chartTypes = ['pie', 'doughnut', 'bar', 'column', 'line', 'area', 'scatter', 'radar', 'stacked_bar', 'percent_stacked_bar', 'stacked_column', 'percent_stacked_column'];
