I took 2 single gas scuba dives and both registered as apnea and apnea hunt dives. During the dive I was confused with the data because the format is all wrong and no deco info and safety stop feature were activated. When I checked post dive, it seems my dives were considered 1hr 1 dive each apnea dives. Am I missing a setting? I didn't change anything from last dive as far as i know.
