Was anything disputed? I've had similar alerts like that where the two scores didn't jive. It was explained to me that a score alert caught a score drop but the drop was only temporary and by the time I pulled a new report, the higher score was showing. Basically it's an outdated score alert. IME, it was due to a dispute dropping the score only to be reversed when the dispute cleared.
Nope, I haven't disputed anything. I haven't done anything credit-related to cause this. Hmm.
