Removing Zotero-only fields

I imported my Zotero library to Paperpile and notice that these two fields were included:

  • Created: mmm dd, yyyy
  • Last modified: mmm dd, yyyy

In Zotero these record the dates that the record was created and last updated. As far as I know Paperpile does not support these fields for its own records, and on import they have all been set to the date of import anyway, so I am not sure of the usefulness of their inclusion.

My main question, however, is: how do I delete them?


No, actually these are Paperpile fields. They are required and can’t be deleted.
