Text offset left after word wrap

[ChaseYI]

I set align ='center'，when the text wrap width, does not reach wordwrapwidth, everything is normal.But when the word wrap is triggered, the whole text shifts to the left. I checked the X coordinate of textcontainer ，It is less than 0.
Before word wrap

After word wrap

How should I set it correctly.
Thanks!
