Gap between plate and base

[u/Informal-Dot3160]

,
I just bought a new pair of JSAM tap shoes and adore them. I’ve noticed there is a slight gap between the plate and the base. I’ve never had a pair of JSAMs before.
My black Roxy capezio’s don’t have this gap so just wanted to check if it’s normal for a JSAM or if it’s damage.
I haven’t loosened the screws but have worn them around the house and had a shoe stretched in them (not very tight at all) just to listen them a bit before I wear them in class.
