In the old editor, templates/blueprints have an option to add instructive text and the option available is Instructional text. However, in the new editor, the option name has been changed to Placeholder text which translates to a different name/nonmeaningful name for Spanish users.

Instructional text - Texto instructivo
Placeholder text - Texto marcador de posición (this actually means text to mark/point/highlight a position)
