Mavic Pro Battery

Hi, question… I put one of my battery on charge, it will not stop flashing repeatedly one to four, I press the button but does not stop, it’s as it is not fully charged, but if I disconnect it and check it I get all full light come on, also if I reconnect to charger it will not charge as its fully charged already, this only happens to one battery , the other will turn lights off once it’s fully charged…any ideas???
