Additional field does not display a preview of the picture?

Question

MODX

Hello, I'm making a website. I made a template Category of goods, inserted there:

[[!getPage?
         &elementClass=`modSnippet`
         &element=`getResources`
         &showHidden=`1`
         &parents=`76` 
         &tpl=`tovar` 
         &limit=`100`
         &sortby=`menuindex`
         &sortdir=`ASC`
         &includeContent=`1`
         &includeTVs=`1`
         &processTVs=`1`
         &parents=`2`
         &hideContainers=`1`
         &includeTVs=`oplata`
    ]]

Where product is a chunk of my design and in it:

<!-- Начало товара -->
 <div class="col-sm-4 product-ots square">
 <div class="product">
 <div class="product-img">
 <a href=""><img src="[[pthumb? &input=`[[+tv.image]]` &options=`w=330`]]" alt=""></a>
 </div>
 <p class="product-title">
 <a href=""></a>
 </p>
 <p class="product-desc"></p>
 <p class="product-price">[[*oplata]]</p>
 </div>
  </div>
<!-- конец товара -->

Question: why doesn't the additional field oplat a display? Although it is registered in the admin panel and in the product card it is
PREVIEW

Decided to cut in.
Then we are given
a placeholder [[+tv.oplata]]
