I have tested that and it works on my machine. Please note that I have tested against the 2011.1.411.2 version.
Can you please share with me how did you remove the table from your model?
What I did is right click on the table and say Remove Table. After that I updated from the database and chosen only the removed table. Upon clicking finish the table was present in the model again.
