Edit Order Placed in Marketpress

I had a product entered twice and ultimately ended up with a wrong SKU on the 2nd product. By the time I realized this error and deleted the product a client had placed an order with the wrong SKU. I went into the database... WP-POST then post type and found the post for the order. I changed the SKU number there but it didn't reflect in the manage orders section. I'm sure this should be an easy fix but don't know what to try next. Hopefully @Aaron @Timothy @GinaB or @PCwriter can be of some assistance.
Thanks!
