Displaying total results from plugin - shows total on each loop

Not sure if I am misunderstanding the way this works…

I’ve been reading the docs at http://expressionengine.com/public_beta/docs/development/usage/template.html

I have followed this in the example below, and am getting results back, but the total_results tag is being shown for each loop, suggesting that I haven’t got my array of “properties” set up right, since it’s outside this loop and I thought it should have only been shown once, followed by all the properties.

{exp:rentpro:search}

    {total_results} results
    
    {properties}
        <strong>ID {property_id}:</strong> {address1}<br>
        {address2}<br>
        {town}<br>
        {county}<br>
        {postcode}<br>
        <hr>
    {/properties}

{/exp:rentpro:search}

Am I understanding this right? Should I be able to get the following:

3 results

Property 1 (shortened for clarity)
Property 2
Property 3

What I am actually seeing is:

3 results
Property 1 (shortened for clarity)

3 results
Property 2

3 results
Property 3
