When you first enter a world, the F2 emote is on by default, instead of F1, but only for others and not yourself. It is only fixed by pressing a different emote, and then pressing F1. This can cause issues like playing music that only others can hear, causing objects that are only supposed to appear when pressing F2 to appear by default, and changes your face to an unintended emote. This happens to both VR users and Desktop Users.
