SW 2011 to 2012: bug in revision table text and file property

I just change from SW 2011 to 2012. When a open a drawing from 2011 in the 2012 version, all the text in the Revision table is gone, the text  for the part properties (part name, description, etc.) is also gone! See attached picture.

There is also a question mark at the beginning of each remaining annotation with text.

I also saw that some annotation with leader were completely out of the drawing (miles away).

Does any body ever had that bug and found a solution?
