Blocks in Blog post.html template not available in post page

I have an issue with when using Blocks in the blog templates.

I have 5 blocks with id's: label="Sub Titles" label="Feature Image" label="Text" label="Images" label="Pull quote"

In the post input screen only three blocks are available to choose from: +Text +Images +Pull Quote

The Sub Tltles and feature image are missing.

I tried swapping the Sub Titles and Feature Image Blocks so that they were 4th and 5th in the blocks list and then I got +Sub Titles +Feature Image + Pull Quote
Again only three and again in reverse order compared to in the template. But also now the content I put in for any TeXt and Image fields has disappeared from the input page. It is still there because when I reverse the code back to the original order of blocks the missing content comes back.

Why can I only get 3 of the 5 block fields to show in the content input page?

Here is the code

<h1><perch:blog id="postTitle" type="text" label="Title" required="true" size="xxl autowidth" order="1" /></h1>
<perch:blog id="excerpt" type="textarea" label="Excerpt" suppress="true" size="s autowidth" order="2" />

<perch:blocks>

    <perch:block type="text" label="Sub Titles">
      <h2><perch:blog id="postSubTitle" type="text" label="Sub title" size="xl autowidth" /></h2>
    </perch:block>

    <perch:block type="image" label="Feature Image">
        <figure class="FeatureImage">
          <img src="<perch:blog id="FeatureImage" type="image" label="Feature Image" />" width="100%" alt="<perch:blog id="FeatureImageCaption" type="smarttext" label="Feature Image alt text" />" />
        </figure>
    </perch:block>

    <perch:block type="text" label="Text">
        <perch:blog id="content" type="textarea" label="Text" editor="redactor" html="true" imagewidth="400" imageheight="300" />
    </perch:block>

    <perch:block type="image" label="Images">
        <figure class="contentimage">
          <img src="<perch:blog id="contentimage" type="image" label="Images" />" alt="<perch:blog id="caption" type="smarttext" label="Caption" />" />
          <figcaption>
                <perch:blog id="caption" type="smarttext" label="Caption" />
          </figcaption>
        </figure>
    </perch:block>

    <perch:block type="quote" label="Pull quote">
      <blockquote cite="<perch:blog id="cite" type="text" label="Web address where quote is from" size="xl" />"  />
        “<perch:blog id="quote" type="text" label="Pull Quote" size="xl" />”<br /> 
        <span class="quoteauthor"><perch:blog id="quoteauthor" type="text" label="Quote attributed to:" size="xl" /></span>
      </blockquote>
    </perch:block>
