Answer 1

I managed to fix this, but overriding the default template of the plugin, I needed to have two templates which differences in one, so essentially, a template which has code for my homepage and for another page.
The homepage has the changes, and the other page does not, and it uses the default theme template.
Here was my solution to having two templates in one using the plugin code.
<?php
// Can be overriden in your theme as entry-content-wpt-test-fill-form.php
/* #var $answerIdName string */
/* #var $answerIndex integer */
/* #var $isShowContent boolean */
/* #var $formAttributes array */
/* #var $content string */
/* #var $subTitle string */
/* #var $shortDescription string */
/* #var $test WpTesting_Model_Test */
/* #var $questions WpTesting_Model_Question[] */
/* #var $isFinal boolean */
/* #var $isMultipleAnswers boolean */
/* #var $submitButtonCaption string */
/* #var $stepsCounter string */
/* #var $wp WpTesting_WordPressFacade */
/* #var $hiddens array */
?>
<?php if (is_front_page()): ?>
<div class="home-health-insight wpt_test fill_form">
<div class="answers">
<div class="content">
<form
<?php foreach ($formAttributes as $key => $value):?>
<?php echo $key ?>="<?php echo htmlspecialchars(is_array($value) ? json_encode($value) : $value) ?>"
<?php endforeach; ?>>
<?php if ($isShowContent): ?><div class="content" style="margin:0;"><?php echo $content ?></div><?php endif ?>
<?php if ($shortDescription): ?><div class="short-description"><?php echo $wp->autoParagraphise($shortDescription) ?></div><?php endif ?>
<?php $wp->doAction('wp_testing_template_fill_form_questions_before') ?>
<div class="question">
<div class="question-titles">
<div class="question-labels">
