VR applet isn't showing the correct controller when using Windows Mixed Reality, and controls aren't working properly

Hello, I’m trying to use the VR application on my Windows Mixed Reality device. More specifically, my HP Reverb G2. It loads properly, but it shows a Vive Wand controller instead of a Windows Mixed Reality controller, and I can’t scale models.

I had it work in the past where it showed a WMR controller, and scaling was done using the analog stick. It does the same thing whether I use Microsoft Edge or Google Chrome. Can anyone help me?
