Incorrect Total on COD Order

I've installed the CVS version of e-commerce on an uncustomized Drupal 4.6.2 site, with COD as the only payment method. I'm using the editasnew and relativity modules to handle variations within a product (http://drupal.org/node/14068). The cart maintains the correct balance at all times, however when it comes to the Please Review and Submit Your Order page, the total is always that for 1 item per selection, regardless of what the actual quantities are. For example, the following should be $31.50 (as it appears in the shopping cart on the same page):

Order Summary

2 orders of Neon Laces (Orange, 108 Inches) at $4.50 each Update or delete?
5 orders of Neon Laces (Pink, 96 Inches) at $4.50 each Update or delete?

Subtotal: $9.00
