Blocks - Missing Content in Admin

Here is a section of the code that I use;

    <perch:blocks>

        <perch:block type="HomePageSlider" label="Home Page Slider">
            <perch:template path="content/blocks/HomePageSliderImages.html" />
        </perch:block>


<!--
    Green Banner Start
-->             
        <perch:block type="BannerGreen5050" label="Green Banner 50/50">

            <section class="bg01">
                <div class="container">
                    <div class="line"></div>
                    <div class="row">
                        <div class="grid_7">
                            <h3><perch:content id="HeaderText" type="text" label="Header Text" /></h3>
                        </div>
                        <div class="preffix_1 grid_4">
                            <p class="mt2">
                                <perch:content id="ParagraphText" type="textarea" editor="ckeditor" html="true" markdown="false" label="Paragraph Text"/>
                            </p>
                        </div>
                    </div>
                </div>
            </section>

        </perch:block>

<!--
    Green Banner End
--> 
      </perch:blocks>

The problem that I have is that the blocks appear in the page editor page in the back office. When you click on one to add it to the page, there is nothing in the page;

example

Any ideas?
