MacBook Air M1 keyboard backlight

Is the auto brightness for the keyboard light supposed to turn it off when I'm in a low light setting? On the MacBook Air 2020 (before the M1) the keyboard light would get brighter and darker, but would never cut completely off in low light setting. On the M1 it shuts all the way off. Am I doing something wrong? It's kind of strange that it would cut completely off in low light, because that's usually when the keyboard light is needed. Is turning off the auto brightness the only way to keep the keyboard light on in low settings?
