When you open your Bookmarks it shows the scripture along with an extract of the verses, so that you can read what the scripture says. Sometimes the scripture is showing the extract from the wrong Bible version, or in the wrong language. Why is that? The extract is pulled from your "Preferred Bible". By default when you install the app the Preferred Bible is the World English Bible (WEB). But when you install a new Bible, the EPUB Settings window appears - and you have the option of changing the Preferred Bible. Otherwise you can go into Admin (top/left) > Bibles > locate the Bible you like and in the Settings window for that Bible you can enable it as your "Preferred Bible". The next time you open your Bookmarks the extracts should have regenerated for your newly selected Preferred Bible.
