Shades device STOP not doing anything

I am working on an integration to Crestron Home.

When working with a shade that only has open/stop/close I am unable to trigger the bond bridge’s blue light when stop is requested. Below are the http rest requests.

Open/Close work as expected causing the blue light to blink. Stop does not cause the light to blink.

Using the mobile app (iphone) all three “circle” button presses causes the light to blnk.

Is there a bug or a misunderstanding on my part?

Thanks in advance…
