Order items keep grouping

Orders are being grouped together. For example, an order containing four unique products might generate a notification email like this:
You have received an order.
Order ID: 2329
Date Added: 19/11/2014
Order Status: Pending
Products
4x Fireball E-Juice (523020d6cfae6) $31.96
Order Totals
Sub-Total: $31.96
Free Shipping: $0.00
Total: $31.96
------------------
Instead, the order SHOULD have looked like this:
You have received an order.
Order ID: 2340
Date Added: 19/11/2014
Order Status: Pending
Products

I'm working on trying to figure out some fixes, but I'm at a loss. I would surely appreciate any pointers to possible solutions. I've checked the OpenCart that may be causing items to be grouped in the orders, but so far I haven't found anything like that. I've looked in the /shop folders, but because I'm pretty new at the OpenCart api, not too sure where to look at. Either way, thank you in advance.
