Shipping.ByWeight Edit Bug

When trying to edit Shipping by weight values all styling and formatting disappears and the update command does not work.
This is Critical as it means if a value needs to change the system will "crash".
The Delete command also does not work and causes the same effect.

Replication information:
Go to Shipping Rate Computation Methods
Configure Shipping By Weight
Add more than one entry ie
     1. weight 0 - 250 and charge 1
     2. weight 251 - 500 and charge 2
Then edit Entry nr 2

I have replicated this on your store demo site also.

Nevermind, I fixed it myself.

The problem is in the controller line 80 where it initilaizes model.Records in Configure().

Fix:
Comment out Lines 80 - 108 where it initializes model.Records.

RatesList method should compile the list and not the above mentioned controller action.

For now it seems to work.
