Materials List "Size" line items do not match components tab

[Design20]

So I am trying to develop my template plan optimizing for material lists.  I am having an issue: the Deck Material List "Size" line items for the Deck Stair Jacks and Aluminum Deck Stair Railing does not match its corresponding values in the deck stair components tab; namely, the formula does not evaluate in the materials list like it does in the components tab.  I hope I'm explaining it clearly enough.  You will (hopefully) see it for yourself in the plan.  I know this is probly a pretty niche problem, but I'm sure one of you macro/Ruby wizards can help me.
