Lead nut off lead screw on Grizzly GO453z planer table

I bought this planer new, and have had it for about eight months. The table always had some play to it while unlocked, and I thought that was meant to be. I now just discovered that this whole time only 3 out of the 4 lead screws supporting my table are connected. The lead screw on the back left of the machine wiggles when I push on it, and that's the corner of the table that moves, so the nut is obviously not connected. I've used this planer many times and haven't had much issues with use other than snipe, but I can't make adjustments because the table is impossible to get parallel with the cutterhead due to the movememt, it's about 5/100" off.



Im going to call Grizzly technical support, but they're only available Monday through Friday. Does anyone know how to fix this?
