Issue with Keyboard Orientation in Unity 6 and Polyspatial 2.1.2 Bounded Volume

Hi, there! When I was developing an application using Unity 6 and Polyspatial 2.1.2, I encountered an issue with the Bounded Volume. When I clicked on the input box to bring up the keyboard, it popped up normally at an angle the first time, but the second time it popped up vertically to the ground. I believe this is a bug. After I drag the Bounded Volume again, it will pop up normally at an angle, and this cycle repeats. I would like to know if this bug is known and if there is a way to fix it.
