I snagged a set of Crossfire Salt and Pepper shakers on that auction site but...

Would someone who has a set take a look and tell me - does each shaker have a bottom cover with a white insert inside?
The set I got has one nice cardboard box with a Crossfire on it, one clear plastic dust cover, one heavy base, two shakers that each have a silver bottom cover but only one has a white insert.

The white insert appears to be what seals the shaker if you decide to put salt or pepper in them. The bottom cover of the one without the insert doesn't stay on the shaker very well. Should both shakers have a silver bottom cover that says Crossfire and a white disc insert inside that seals the bottom of the cavity?

Any insight from Crossfire Salt & Pepper Shaker owners would be much appreciated...
