I just purchased a O-72 wye and (5) O-72 Left Hand Switches to make a train yard. They programmed fine and switch back and forth ok. The problem lies when I back a train over the switch it switches after the tender causing a derailment? Can someone help me?

Are you saying the non-derailing is malfunctioning? I'm not sure exactly the scenario. I have a bunch of the O72 command switches, and I've never had any issues with them switching at the wrong time.
This might be hard to explain but hear it goes. In the picture I have the Milw Rd engine on the first turn out. The tender went that way but the engine kept going straight. Weird part is, once the tender cleared and the engine trucks hit the switch part physically threw itself, I heard it and watched the light swivel. I double checked the wiring. U to outer rail and legacy base, A to center rail with a cw-80 transformer. I am baffled... It does it every time on all the switches along that straight away but not the wye....

So I tried a plethora of different scenarios which required isolating the switches one at a time. It appears I have one bad switch. For some reason this was causing all of the left hand switches to go haywire? Time to send a email to modeltrainstuff....
Wasn't there a thread about some of these switches being wired backwards in some way...something about taking it apart and exchanging two wires...?
That would be awesome if there is a simple fix... Could be the issue because I was getting continuity between center rail and outer rail?
Since you have one bad switch, I'd just send it back.

Yep, thats what I am going to do.
Thanks for the info. I read through the document, I have a feeling mine is something different. Since its new I am just going to send it back. Thanks for help and posting the info... Jeff
