Why is my Fitbit Charge 3 adding Stairs I didn't climb?

Everyday my Charge 3 is adding "stairs climbed". Sometimes 3 or 4 flights and sometimes up to 17. How did I correct this?

@pslovesbunnies Thanks for stopping by!

Let me help you with this. Your device uses it's altimeter to detect variance in altitude. It will count 1 floor for every 10 ft it detects you climbed. There are situations that may affect the floor count like stormy weather (that has an actual impact on atmospheric pressure), gusts of wind, an AC unit in a closed room or opening a door. I suggest you start by cleaning the back of the device with cotton and rubbing alcohol then use compressed air at a distance to clear the altimeter's opening (small hole on the back of your tracker). Finally restart it.

Let me know how it goes.
