The other 3 with sockets and socket and ball are no where to be found.

Those are in the hinge plate group. I thought I moved all the ball plates there too, but this seems to have fallen trough the cracks.

But if you defined a custom group it doesn't really matter if they are visible somewhere else too, group content doesn't need to be unique.
