I've been a myFICO Premier subscriber for almost 2 years now, and have never seen this before.
I just pulled my monthly 3B, and all the report account data is correct and exactly what I expected this month.
There is no report data to dispute here.
But my EX 2 score is down -2 points and the reason statements shown are:
The 3B report is correctly showing 2 of 4 revolving accounts with balances: $189 and $1,234 for a total of $1,423 aggregate balance (4%).
This seems like a problem with the EX 2 scoring module, and I'm unsure of where to report that.
