Vive Cosmos left shoulder/bumper button not working

[Wababa]

Hi,

I am working on an Unity 2022.3 project with OpenXR 1.8.2 and I am unable to get the left shoulder button of the Vive Cosmos to work. I have downloaded the latest 2.0.0 release and modified the Input sample scene as shown here: https://forum.htc.com/topic/9141-vive-cosmos-controller-openxr-feature-for-unity
This works perfectly fine for the right shoulder button but the left one does not work at all.
One thing I have noticed is that once the above mentioned scene is tested with both the shoulder button displays set up, when you press the left menu button, the left should button slider appears to move very quickly to one side and back to the initial position. This could also just be a visual glitch of some sort.

Thank you.

Quick follow up:
I noticed that if I start the modified sample scene with only the left controller turned on, the shoulder button works fine. If I then turn the right controller on, it stops working.
