Transform of instances

Hello. I have a trouble with bifrost instances in Maya.

 

I created following simple graph which places 100 instances of the red cube on the surface of the  sphere.

It works fine.

But the transform node in Maya is moved or rotated, the instance alignment is disrupted as shown in the following picture.

Such disruption only occurs on viewport. The rendering result with moved transform node is what I expected as following.

In the viewport, the transformation of the bifrost graph seems to be applied after transformation of each instance.

Once I convert instances into geometry using bake_instanced_geometry node, the display in the viewport and the rendered result will match.

 

Is this a bug? or I make some mistake?

I use Bifrost 2.2.0.1, mtoa 4.1.1.1 and Maya2019.2.

Thanks.
