Scrivener on iOS is putting my text in bold and italics by default

I’m moving between Scrivener in Windows and in iOS. My preferred font is Cambria, which didn’t seem to be supported by iOS (it was defaulting to Helvetica), so I put the files for Cambria in Dropbox and got my document set to it and also set it as the default for iOS. This seemed to be working fine but now whenever I open up a document in iOS, using Cambria, it has put all the text in bold and italics. Does anyone know why?

I should add that this switch to bold-italic on iOS happens after I’ve been using the synced file on Windows (in regular Cambria)
