This will not answer your question directly but provide you with a possible alternative which could be a workaround for any text formatting issues with your current setup.
If you are not too far down the path of writing then you might want to look at LaTeX environment and TexStudio editor which would allow you to create professional quality books from scratch and only start worrying about the presentation once you are far enough in the process. You start off with just structuring your document, then you can add tables, charts, graphs, illustrations, title pages, TOC, LOF, LOT, etc.
It is multi-platform as well and you can work on the same document on almost any device in the world as long as the TeX distribution is not too old. I often work under Windows XP, but also under Windows 10, FreeBSD, and modern Linux.
PS: I do not know if Scrivener is well represented on SE. The advantage of LaTeX is that there is a site for it here and it is one of the best resources that Internet ever had.
