Don't delete/remove it, do it Inactive.

Move block or item down to Inactive block or Inactive Item and drop it there.

OK. Thnks. But how can I replace for example ... in Fields Builder - Misc Info - Headline. I clicked it and there is a field "Name: HEADLINE" . I can't modify or replace it. How can I replace that field ?

if it is in the Active section , click it ,  you will see the field : Headline  , write what ever you want to replace it with, then click save ,
