How to reset the default anchor point of a text?

Recently I found that the default anchor point of the text layers has changed. It used to be at the bottom center of the text but now it's far below the text. 

It means that if I click the middle of the composition and type the text, it will apper at the top. It happens every time. I can manually center it for one text, but it will happen again next time. It's supper annoying. Does anyone know how to fix it?
