I was just going over "the books" when I noticed what I first thought was a charge from my old defunct Cobalt Card. But, on closer inspection, it is actually a credit of the remaining $18.31 that was left on the account. Looks like they simply picked a card that I have linked to the Cobalt Card and sent a credit back to it. Lesson: if you haven't received that little refund check back from you defunct AMEX Cobalt Card yet, check your CC statements.
