Animation window on the right with content.

Hello there. During the opening of a window, I created an animation for what happens to the right. It works but the window contents move too. I do not know why?

var self = Ti.UI.createWindow({
    backgroundColor:"white",
    top:40,
    fullscreen:true,
    left:1000,
 
});
/////////////////////
 
var win = new ui.NewPage(e.rowData.sessionObject);
var slide_left =  Titanium.UI.createAnimation({duration:700,left:0});
win.open(slide_left);
