MarketPress – Sub-blog orders showing up on main blog too

I’m having a strange issue with Marketpress 2.1.1.

Whenever someone orders a product from one of my client’s sites (i.e. a sub-blog store), I’m also getting an email. And the order is showing up on the main blog as well. That shouldn’t be happening.

The order looks fine on the client site (under Manage Orders), but it’s showing up garbled on the main blog.

Here are a couple of screenshots:
