I went through this in my hallway closet too and mine always flicked on around 2 a.m. with the door shut. It turned out the overnight HVAC cycle pushed a slow draft through the door gap and the PIR saw that moving temperature change as motion. Lowering sensitivity and recharging did nothing and taping a sleeve didn't help either. What finally worked was two quick tweaks. I rotated each light so the sensor faces a solid surface like the back wall or a shelf, not the door or hanging clothes. Then I masked the outer edge of the PIR lens with a thin crescent of black electrical tape to narrow the field of view. Diffuser tape did not help since PIR sees infrared, not visible light, so you need opaque tape or foil. I also added thin weatherstrip on the door stop to kill the draft. After that I stopped getting ghost activations. If yours still misbehave, I replaced one with Gritin 10.2inch and it's been calmer in the same closet. The four modes let me run a true night motion setting and the five brightness levels keep it low so it isn't blinding when it does trigger. Only minor gripe is it's a touch longer than my old bars, but it's been solid. Quick checklist that helped me finish the job fast. Aim sensors at a wall or floor. Mask the lens to narrow the view instead of covering the whole thing. Add a sliver of door weatherstrip to stop the draft. Keep the auto off time short to save battery if it ever does trip.
