Report Generator with Word Rich Text Format keeps producing XML parsing error

I've got a script that opens a word template (dotx) with RTF and goes from hole to hole appendeding data to the holes. (Same workflow as in the introduction video for the report generator: https://www.mathworks.com/videos/introduction-to-matlab-report-generator-1530193853139.html)

It worked fine at first, but after a while I would try to open the docx file that it would produce and I would get an XML parsing error. (/word/document.xml, line: 2 column:65806)

In general, my code looks like this:

import mlreportgen.dom.* 

run DataImport.m
rpt = Document('Report','docx','ReportTemplate.dotx');
open(rpt)

moveToNextHole(rpt);
append(rpt, data1);
moveToNextHole(rpt);
append(rpt, data2);
%This goes on for several pages

close(rpt)

My big question is whether this is a problem with my code or the word template. I found that if I shortened my code (closed rpt say, before appending data2) it would open just fine (but of course the report is not finished). I tried running the docx file through Yodot doc repair and that didn't do anything.

I noticed that the problem occurs after a block hole while everything else up to it has been an inline hole
