New Post: Office 365 - Not found in relationshipList

I've been using this library extensively on an on-premise environment and it has been working wonderfully, but I'm having problems on Office 365 and I can't figure out what I'm doing wrong. I'm getting the same error for both the SPFilterDropdown and SPCascadeDropdowns. This is the error message I'm seeing:

Error in function
SPServices.SPCascadeDropdowns
Parameter
relationshipListParentColumn: Name or
relationshipListChildColumn: Position
Message
Not found in relationshipList Candidates

I've tried this on a few different lists with different fields types, I even tried using the GUID instead of the list name, but I get an error for every single column. Below is my script for SPCascadeDropdowns. Is there anything I should do differently in Office 365?

<script language="javascript" src="/SiteAssets/jquery-1.11.1.min.js"></script>
<script language="javascript" src="/SiteAssets/jquery.SPServices-2014.01.min.js"></script>
<script language="javascript" > $(document).ready(function() { $().SPServices.SPCascadeDropdowns({ relationshipList: "Candidates", relationshipListParentColumn: "Name", relationshipListChildColumn: "Position", parentColumn: "Candidate Name", childColumn: "Position", debug: true }); }); </script>
