Floor count is through the roof

Since about the beginning of January 2023 my Venu 2 has started showing climbed floors totally wrong. Before it used to be fairly accurate but now I get more floors throughout the day even if I definitely don't climb at all. For example today I got 20 floors just by being at work sitting and occasionally walking a bit. In reality my floor count should have been about 4-5. I may even get floors when driving a car or riding an elevator. Before the watch was able to recognize that I wasn't walking on those situations but it seems that now every air pressure change results in generous amount of floors climbed.
