Hi, pavera, welcome to the forums!
You actually have three FICO scores, one from Equifax (EQ), one from TransUnion (TU), and one from Experian (EX.) I'm guessing that you pulled your EQ score through ScoreWatch, or possibly your TU score through the Quarterly Monitoring product.
Every now and then, one of the CRA's (credit reporting agencies; credit bureaus) goes into some sort of funk and doesn't update anything at all. This seems to be a problem especially with TU, which can get months behind.
But at the same time, the CCC's (credit card companies) themselves also get sloppy about reporting. When you put the two together, you can find yourself pulling your hair out.
It should fix itself eventually, but if you get down to the wire at mortgage time, you might have to dispute the balances with whichever CRA is behind. On the other hand, if the same account is late on all three reports, and all the other scores are reasonably current, then it's probably the fault of the creditor, and you'll need to get on the phone with them. Good luck, and hope that helps.
