Help me get Variant manager working with Sony's Spatial Reality Display

I am creating content to view in Son’y’s Spatial Reality Display. My variant manager /configurator product is otherwise working when not being played via VR preview mode in Sony SR display, but whenever I try to play it by Vr preview mode, the 3d depth is displaying fine but the position of variant manager buttons are haywire and they aren’t getting click either. it looks like the mouse cursor is hovering on different plane than the buttons
