Right Justification of Text

In Scrivener, the text of my document is not right justified - the text is “ragged right.” But when I compile as ePub and review the text in iBooks and Kindle, it is right justified.

Does anyone know if the Scrivener Compile process is causing the right justification (and, if so, how to turn it off), or whether it’s the ebook reader? Thx

It’s the ebook reader. On some it can be turned off.
