Garmin Descent MK3 up button or software issue?

I recently received my first Garmin ever, Descent MK3 43mm.

During navigating through the menus I have noticed strange behavior with the up button. Sometimes the watch will continue to scroll up once or twice without a press of the up button.

In the video look at third and the last press of the button.

Is this a button or software issue? Is it something happening in Garmin watches in general?

I am thinking of returning the watch as I can do so within 30 days.

Other than that I love the watch so far.
