Why is thickness not updating in a Sheet Metal reducer part?

I have this part from 2009 which is a concentric reducer(same problem with another eccentric reducer). When SW 2011 was implemented, the thickness in the design table no longer updates the model. I'll have to manually go to the model and edit the feature. I have attached the part if anyone has any idea on how to fix this problem.

Trying to help out John Wang.

I'm not sure if this is the "correct" answer, but I got it to work by adding Thickness@Sheet-Metal1 to the table and changing it along with PL Thick.@Lofted Bends1. See screen caps.
