WPAllImport XML issue

Source Joomla website renders correctly:
http://www.truth-out.org/article/item/42794

In Joomla content in MySQL before export:

<div><span class="wf_caption" style="display: block; max-width: 640px; width: 100%;"><img src="http://www.truth-out.org/images/Images_2017_12/2017_1204td1.jpg" alt="(Image: Muhammad Ansi, Untitled (Pier), 2016.)" width="640" style="width: 100%; margin: auto;" /><span style="margin-top: 3px; display: block;">(Image: <a href="https://www.artfromguantanamo.com/muhammad-ansi-1/" >Muhammad Ansi</a>, Untitled [Pier], 2016.)</span></span></div>
<div>&nbsp;</div>  

In XML export file: 

<field name="post_content">&lt;div&gt;&lt;span class=&quot;wf_caption&quot; style=&quot;display: block; max-width: 640px; width: 100%;&quot;&gt;&lt;img src=&quot;http://www.truth-out.org/images/Images_2017_12/2017_1204td1.jpg&quot; alt=&quot;(Image: Muhammad Ansi, Untitled (Pier), 2016.)&quot; width=&quot;640&quot; style=&quot;width: 100%; margin: auto;&quot; /&gt;&lt;span style=&quot;margin-top: 3px; display: block;&quot;&gt;(Image: &lt;a href=&quot;https://www.artfromguantanamo.com/muhammad-ansi-1/&quot; &gt;Muhammad Ansi&lt;/a&gt;, Untitled [Pier], 2016.)&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div&gt;&amp;nbsp;&lt;/div&gt; 

In WordrPress after WPAllImport:

<div><span class=&quot;wf_caption&quot; style=&quot;display: block; max-width: 640px; width: 100%;&quot;><img src=&quot;http://www.truth-out.org/images/Images_2017_12/2017_1204td1.jpg&quot; alt=&quot;(Image: Muhammad Ansi, Untitled (Pier), 2016.)&quot; width=&quot;640&quot; style=&quot;width: 100%; margin: auto;&quot; /><span style=&quot;margin-top: 3px; display: block;&quot;>(Image: <a href=&quot;https://www.artfromguantanamo.com/muhammad-ansi-1/&quot; >Muhammad Ansi</a>, Untitled [Pier], 2016.)</span></span></div>
<div>&nbsp;</div>

WPAllImport has correctly converted the XML's &lt; and &gt; to < and > but is failing to convert &quot; to ".

Images and inline styles are broken in the WordPress HTML (ignore the Featured Image at the top, that's not an image in the body):
