When I drop my panel in non drop zone the Extjs animate the drag element back to the source element in wrong directions, how to fix this behavior?

Here is my code for Dragzone and DropZone, when I change my app to LTR it just fine, and when I switch it back to RTL then the issue appears again.
function calEventPnlSourceDD(sender){
sender.mX=sender.getX();
sender.dragZone = new Ext.dd.DragZone(sender.getEl(), {
ddGroup: 'dgCal',
getDragData: function(e) {
var sourceEl = e.getTarget(sender.itemSelector, 10);
if (sourceEl) {
/*sourceEl=sourceEl.parentElement;*/
d = sourceEl.cloneNode(true);
d.id = Ext.id();
return {
ddel: d,
sourceEl: sourceEl,
repairXY: Ext.fly(sourceEl).getXY()
}
}
},
getRepairXY: function() {
return this.dragData.repairXY;
},
onDrag: function(e) {
}
});
}
function calEventPnlTargetDD(sender){
sender.dropZone = new Ext.dd.DropZone(sender.el, {
ddGroup: 'dgCal',
isDropAllowed: false,
getTargetFromEvent: function(e) {
return e.getTarget(sender.rowSelector);
},
getAllowed: function(e) {
var proto = Ext.dd.DropZone.prototype;
var tg=e.target;
this.isDropAllowed=true;
return proto.dropAllowed;
},
notifyOver: function(source,e,data) {
return this.getAllowed(e);
},
onNodeDrop: function(target, dd, e, data) {
return this.isDropAllowed;
}
});
