Problem with WPG2 3x

Hello, I have a light problem:

Since I upgraded to WPG2 3x, in the WYSIWYG WordPress (2.2 version), when centre images with the editor by pressing the button, I centre image and WYSIWYG writes “<div> https://blabla.com/imag.jpg </div> “, but that syntax is not correct, because when the public does not appear centered. Previously, the WPG2 2x not the case this problem, I just had to press the button and focused manner with the correct syntax “<p align=center> https://blabla.com/imag.jpg </ p>” appearing centered image when it publishes the post.

Someone can help me? thank you.
