title: re.findall() was working but now isn't finding the pattern I need
body: <p>To preface I am working in Python 3.8.3 on windows 10 and using <code>slate3k</code> to parse through my pdf</p>
  
  <p>I am working on a python program that will parse through a PDF and spit out a certain pattern and make a csv file for me.</p>
  
  <p>However, when I try find the pattern with the parsed text, I am getting nothing.</p>
  
  <p>I've taken an example of some parsed text and assigned it to <code>parsed</code></p>

  <p>I had this pattern working in a previous iteration but I am having issues here. Any insight as to why it isn't working for me now would be greatly appreciated.</p>
  
  <p>Edit:</p>
  
  <p>I was expecting a list of <code>['81PEW1002', '81PEW1003', '81PEW1004'... etc]</code></p>
  
  <p>There are two distinct patterns I am trying to catch:</p>
