They ran Experian and Transunion - I got 740 on Experian and 640 on TransUnion. Seems nuts. They are using the higher one, so it doesn't really matter, but the discrepancy is huge.
Have you pulled either report and compared them side by side, it's possible something is reporting that should not be.
There's something up. Explicit is right: you should pull your reports and compare them. There's something (some kind of baddie to be specific) on TU that's not on EX, I can almost guarantee it.
