Why my steps count reduced automatically in the app?

It could be that the app assumes that just wandering around your home will give you a minimum of 2000 steps. That is part of your basic activity level (if set to sedentary, I assume) so wouldn't count as extra exercise. If your level was lightly active, then 5000 steps would be daily activity rather than deliberate exercise.

FWIW, I've noticed my watch adds steps when I pet the dog or drive the car. I don't have my watch linked to MFP since I don't consider those active calories. I just log my deliberate exercise (walks, runs, bike rides, etc.) manually. I've noticed that the burn rate from my watch is a little higher than the number given by MFP, but I'd rather underestimate my exercise than overestimate it.
