Seat moves back and forth slightly

[Androidrc]

I did some searching and just figured i'd see if anyone else had this issue. I have power adjustable seats but after i move it to the appropriate forward and backward slide position, it seems as tho it is locked in that position but it still slides back and forth (front to back) about 2" freely. In the grand scheme of how much i love this car it's not that big of a deal but it does seem like it needs addressed. Any suggestions at all would be appreciated. thanks.
