It would help to know exactly what you are transcribing? Is this an alphabetic reference (since you are using the rules for alphabetic references)? If so, you need guide words.
You did handle the margins correctly for page 31. And adding a colon to separate the two languages is also correct.
Does the heading Adjetivos begin a new section? It might be wise to start it on a new braille page (each alphabetic reference begins on a new braille page). But to answer your question, I do not believe you need to adjust the heading over based on the articles. You do have words that start at the margin...I might suggest that you post that question on the Foreign Language forum.
