My bracelet has a click sound when I push it and a bit of a gap as well. I was a bit worried at first but I've never had an issue with the screw for the 3 months I've had mine (fingers crossed it stays that way).
Mine does not have that big of a gap, I would look into it. Definitely don’t want them glueing it, that’s for the classic bangle. Thin love should be able to be taken on and off, so no glue for this one.
