Subproducts API creating a product for each attribute, and "user warning" errors

Hello, I'm workin on 2 sites that have the same setup and e-commerce configuration. Yet they are behaving quite differently. Site 1 ( http://nativecoffee.info/ ) works the way I expect it to, with the exception of one small glitch which I've posted about at http://drupal.org/node/123629

On site 2 ( http://organicgrace.info/ ) I am adding products the same way as I did with site 1. The first problem is that the subproducts API was creating a new product in the taxonomy for each of the attributes of the variation type. I am creating 1 product and am getting 3! You can see what I mean here: http://organicgrace.info/taxonomy/term/1

The other problem is that there are many errors have popped up in pages. They go generally like this:

user warning: Table 'ekai_ekai.organicgrace_ec_shipping_product' doesn't exist query: SELECT service, method FROM organicgrace_ec_shipping_product WHERE vid = 18 in /home/ekai/public_html/includes/database.mysql.inc on line 172.
user warning: Table 'ekai_ekai.organicgrace_ec_shipping_product_attribute' doesn't exist query: SELECT field, value FROM organicgrace_ec_shipping_product_attribute WHERE vid = 18 in /home/ekai/public_html/includes/database.mysql.inc on line 172.
user warning: Table 'ekai_ekai.organicgrace_ec_shipping_product' doesn't exist query: SELECT service, method FROM organicgrace_ec_shipping_product WHERE vid = 17 in /home/ekai/public_html/includes/database.mysql.inc on line 172.

user warning: Table 'ekai_ekai.organicgrace_ec_shipping_product' doesn't exist query: SELECT service, method FROM organicgrace_ec_shipping_product WHERE vid = 19 in /home/ekai/public_html/includes/database.mysql.inc on line 172.

These errors show up both to anonymous users and administrators. Not being a programmer, I don't know if this is a bug or a problem with our server setup. However, I do know that we haven't had any problems like this with sites in 4.7.... Thanks for any help you can give.
