It wouldn’t be capable of using your compile group selection, or filtering settings, from the desktop version (it lacks those features entirely, so it wouldn’t read from them either). Were you perhaps using some other method to select a portion of the draft to compile?
Here are, by the way, the main ways we’ve designed for selecting partials of the Draft for compile. As noted there, one might use the hard, per-item, checkbox setting as well but that’s of more utility to things you’d never ordinarily want to compile, like chapter notes or incomplete sections (and stuff you probably wouldn’t ever want counted either, in stats).
Maybe that’s what you did though? If so, you can access that toggle in the Inspector on the iOS version. Sadly there is no overview of that information anywhere, like there is in the Outliner, or even the compile contents tab, so thus no bulk way of making changes.
