Protected fields

I want to edit an anki cloze card, but their is only one field (Extra) to add my notes to. I don’t want to use this field because my notes will get overwritten if the card gets updated, I don’t want to protect this field because then the note wont get updated. I added a new field but it does not show my text on the back of the card

You’ll need to edit the note styling and add the field to the back template
