Probably no big deal, you just need to reset the "home" position of the chrono hands. That appears to be a Ronda 5020.B movement (very decent unit, btw), here is the manual which includes instructions on re-zeroing the hands.
Unlike a mechanical chronograph where everything is coupled through gears and therefore mechanically "fixed" in place, in quartz watches the chronograph hands are controlled by individual stepper motors, which means that the only thing fixating the hands in place is a magnetic field. Therefore, if the watch is subjected to just the right vibration or shock the magnetic field can be overcome and the hands can get knocked out of place, and this commonly happens during shipping.
I'm able to realign the second hand by pressing A as shown in the pdf. But nothing is happening when I press B
