I noticed yesterday that the "Toggle FBT" and the "Lock" options were missing on the QM.
I hopped in today and first, after turning on the trackers the Sit/Stand button did not update. Although clicking it took me into FBT callibration.
Checking on the IK settings, only the height and the IK 2.0 selector were shown on the menu.
I closed VRChat and opened it again. Now on the IK settings, there were the missing options plus the new selector to show the different callibration visuals.
I believe that the extra button rows do not load in if the trackers are not connected to steamvr before booting up VRChat.
