Hide "Zotero" on the Item Page

Hi,

is it possible to hide the term “Zotero”, as well as “Dublin Core” on the Item pages?
I found how to hide single elements with the Hide Plugin but on the Item page there is the Title Zotero, which I would like to eliminate – see the picture.
Help is much appreciated!

Turning off “Show Element Set Headings” on the Appearance Settings page will get rid of the “Zotero” and “Dublin Core” headings.

Thank you very much!
