I just placed an order with Brick Assortments (thanks khle!), and the PayPal payment is called "Purchase from n/a".
It's not a serious problem, and I don't know if it comes from BrickOwl or khle's PayPal account... but I'll post this in case the little glitch may come from BrickOwl.

In my list of Paypal transactions, I currently see "Purchase from n/a".
And the Paypal email's subject is "Receipt for Your Payment to n/a".
If this is all unrelated to BrickOwl, then khle should probably review his Paypal account's information.
