WTH can’t get back to Home Screen on iOS

Seriously, what the heck. I’m trying to configure some z wave devices and if I click the gear icon onto the zwave settings and then back out of the settings, the back button is an endless cycle of take me back into the zwave settings or back to device info so on so forth, there is absolutely no way for me to get back another level or to the home screen. I have to close the app and reopen it.
