Search Errror Windows 10

1. click on search
2. search for "restoration"
3. clicking on the Alma 11 search results brings up the Title page to the Book of Mormon.
4. The mid-screen left and right arrows take me to Alma 10 and Alma 12 good enough but Alma 11 is replaced by the title page.

I don' think it's windows 10 after all. what ever version this is.

These are screenshots from the older Windows 8.1 (v 2.x) version of the app. The issue you're experiencing here is not with search, but with a damaged copy of the Book of Mormon. You'll need to delete the book, close and reopen the application, and then redownload it.
