I've seen a few people with issues.
One thing I have to say is that the best way should be to use the SteamVR version, however it is set up as a seated experience, I know this sounds a bit silly. The system only let me reset tracking center when I had it set to seated, very weird but that might be the height issue, though it doesn't make much sense.
You might somehow have a way of overriding that, I doubt that is it but it may well be, if it is the tracking origin is at the player's head, if you're in room scale then the origin will be at the floor in the center of your play space, so you'll be a full human higher than the player in game.
If you have more trouble with the SteamVR version and try it through Revive again see if it is somehow overriding the play space, it can't be set to room scale, that will cause the issue above, don't worry about changing it if you can, you still get your full tracking space regardless if whether it's set to roomscale mode or not, it's literally just a different origin point, has no affect on tracking space.
If this isn't the issue please let me know what happens wheb you click the Reset button in the game, do you visibly see the reset happen, it should reposition your entire camera to the center of the menu and rotate you to face the button blocks, if this doesn't happen it should be a playspace mode issue because something is blocking it from doing the reset. If it does reorient but not position let me know, if it does both position and reorient you, tell me if it's higher or lower than it should be.
Thanks, hope it fixes it.
