My silent alarms are not working properly-Charge 3

[lalino]

My firbit is acting weird, my alarm doesn't work sometimes and sometimes I can't see my alarm I have set up alarm for 5:00 (smart wake up) , 5:16 and 18:00, but for the last two months it either not alarming or when I check the alarm it alarm for 7:00, 7:30 and the 18:00 does even shown up. The watch is about two years old from when I got it. What is wrong with it and how can I fix it? I'm really relying on this silent alarm to not wake up my family that are light sleepers
