SharePoint Online - Script Editor throws "item cannot be modified because the site is on hold"

Hi,

I'm trying to add a Script Editor to a Site Page on SharePoint Online. Just a very simple script to print a selected item.

Whenever I try to save the page after adding & configuring the Script Editor to the page, I get "item cannot be modified because the site is on hold or retention"

Our site has to Retention or Holds set up to my knowledge - how I could I be getting this message?
