2. Either go to System -> HUD Layout or use hotkeys and switch to a different preset and then switch back to your preset wich had "Pet Hotbar Display Settings" set to option 1 or 3.
3. Pet Hotbar Auto-Display Settings returns to default "Display only pet hotbar" (2) value, so you have to change it manually every time after you changed your HUD.
