Batch list bug

[Josh Rayburn]

Take a standard base and save off as only a cabinet back
load cabinet back into batch list, quantity 1, change size to something different
change sheet stock from the batch list, change to a different thickness material
click the cabinet back to load it again, quantity 1, change size to the same as the first added item in the batch list
notice the quantity of the first item changes to 2, instead of adding a new item.
this auto-logic fails to examine the material thickness....?
