Sometimes my DetailTableViewModel will have "no back button" in the navBar at a SCPropertyTypeSelection table.

It seems to be pretty random and can happen with any of my properties that use SCPropertyTypeSelection.

Any idea why this occurs?

When it happens, I am stuck on that screen and have to reinstall the app.

That is really strange. Usually the back button title is not handled by Sensible TableView at all, but rather by the UINavigationController (just as in any other app not using STV). The only case I know of where the back button does not have a title is when you don't give your navigation bar a title in MainWindow.xib . Other than that, no one ever reported this problem.
