Weight Distribution Spring Bar Problem

I have a Reese Dual Cam WDH and Sway Control installed and this past weekend when I pulled into the dump station I noticed that my spring bars had popped out of the saddle of the sway control arm and were sitting on the ledge of the control arm versus in the saddle. I pulled around and straightened out and one of them fell back into the saddle while the other did not. I've never watched as i've turned before but I cannot believe that this is normal or safe. My bars are nice and tight and level with the trailer frame and I have 5 links showing so it all seems to be hooked up correctly (trailer and truck are level and wheel well measurements are returned to normal).....looking for any advice you all might have.
