Steps to reproduce

drush si
drush en paragraphs_report -y
Log in as administrator
Navigate to /admin/reports/paragraphs-report/settings
Select Articles content type
Select "Watch for content changes and update report data"
Save configuration
Create a paragrah type called "Text" with one Long Formatted Text field
Add a field to the article content type called field_paragraphs allowing the paragraph type
Create a new article with the required title Test and one paragraph.

This seems to only happen when You have never Clicked "Update Report Data" before.
