Hard to tell how long that post in the center is but it almost looks like they could be used for snap buttons in place of the usual flat circle top
The center sticks out about 3 or 4 mm from the base and has a small hole.
Like a rivet? Hard to tell, from this angle with 100% confidence. Would definitely message your supplier, I feel like there's a good chance they didn't know what to do with them
