Disclaimer:
If a word being translated to a certain language belongs to that language already, WordReference site takes you the inverse translation. For example, if settings are to translate from French to English but you choose to translate the word "suck", WordReference will take you to the translation of "suck" from English to French.
This behavior is inherent to the site and has nothing to do with the add-on.
