Problem with display pages

Hi. I have problem with display other pages on main page.
I wrote two codes for this.

<div class="three-features">
	<div class="container section-padding">
		<?php
        $id = 28;
		$tf_content = get_page($id);
        echo apply_filters('the_content', $tf_content->post_content);
		?>
	</div>
</div>

<div class="product-advantages darker-bg">
	<div class="container section-padding">
		<?php
		$pa_content = get_post_field('post_content', 43);
		$pa_content = apply_filters('the_content', $pa_content);
		echo $pa_content;
		?>
	</div>
</div>

In the main WordPress editor all be good, but if i create content in Unyson, content doesn’t display.

Regards.
