[Wurkkos HD20] Charging indicator LED question – only half of the switch illuminates?

Hi 🙂

When charging my Wurkkos HD20 via USB-C, the blue indicator LED beneath the top switch only illuminates on one half of the button (as shown in the attached photo). Can any other HD20 owners confirm if this uneven lighting is a normal design quirk due to the internal LED placement, or if my specific unit has a defective indicator light?

Thanks! 🙂
