Upon opening my new wall connector, I noticed that the charger wand plastic on the top edge of the button side isn't full secured. When pressing above the button near the top edge, the plastic flexes down and isn't fully secured to the wand. When comparing to my UMC charging wand, the plastic is fully secured above the button at the top edge. Is this normal? I am concerned water may penetrate inside the wand. See pics below. Thanks.
