Joomla Articles *news website* -code fix

Intro in the news articles needs to be fixed it is duplicating the text at the end of the story. Thanks. A small explanation: I discovered that in fact, is not the intro that need fix but the "Read more" capability. I disabled it and the text is not repeating anymore. I still need the style to be fixed. I am looking for a Joomla expert or at least knowleadable developer. WP is not Joomla. If the idea or changin the style sheet for the whole display of the article sound fesable to you, please contact me. My website is a community news space, maily in Spanish.
