This isn't a glitch. That star means your companion successfully stabilised, so he is not dying anymore, but still needs healing to get up.
The icon for being knocked out isn't just an icon if you pay a bit more attention to it. It has 2 counters for stabilising rolls. When one of the counters reaches 3 the character either stabilised or dead. For player convinience Larian also mayde it so all character automaticly stabilise if the fight ends.
