Don;t worry
It just seems that the VR device version has not been updated. For example, daydream and mivr is still 0.1.9, and most of the other platform such as oculus and steam is 0.2.0
There exists the "time" button in sort opitions of the PC version 0.2.1, so I think it will not disappear.
My opinion is just wait for the release update for VR devices
