Not sure this will work, but I would try turning off the HR (it is likely on auto) when you remove it to see if that gets the results you want. If that works, it is the auto feature that is not working well. I have found when I take it off, it sometimes keeps looking for a HR - I have found any movement or any change in light seems to make it think it should be on. Good luck and let us know how that goes!
