If you are citing with an author who's first or surname is multi-text such as John David or De Santos using SmartCite the  add-in will only recognize the first text of the author's name as the first name and the last text as the last name.

Our team is aware of this and our team is working on having the application recognize these names in a future update of the application.

A workaround for this is to copy the space from the following website to be place in-between the text for the first or surname when editing the metadata of the desired article.

After saving the metadata associated with the entry will then recognize it as 'one' text and show it correctly when citing.
