I tried @anhskohbo’s recommendation but it did not resolve the issue. I did notice that there is a difference between an older export file and one I generated today.
For example:
Older export file (XML):
<wp:term><wp:term_id>46</wp:term_id><wp:term_taxonomy>nav_menu</wp:term_taxonomy><wp:term_slug>social-butterfly</wp:term_slug><wp:term_name><![CDATA[Social Butterfly]]></wp:term_name></wp:term>
Same theme, export file from today:
<wp:term><wp:term_id>49</wp:term_id><wp:term_taxonomy>nav_menu</wp:term_taxonomy><wp:term_slug><![CDATA[social-butterfly]]></wp:term_slug><wp:term_name><![CDATA[Social Butterfly]]></wp:term_name>
</wp:term>
It appears as if the <wp:term_slug>
is wrapping the text in with <![CDATA[]]>
. I don’t know if this helps or not. This was just my first quick pass at comparing the two files.
