How to apply zero input delay to NARX Net?

Hello,Dears

I trying to Train NARX Net with zero input dely and 1 feedbackdely.but i imagine the preparets function don't work correctly. XTrain and YTrain are as follows:

when I use preparets function the outputs function are as follows:

[Xs,Xi,Ai,Ts,~]=preparets(net,XTrain,{},YTrain);

As can be seen in the above images, the xtrain has also been delayed.

Can anyone help clear this confusion?
