Do you have more accounts on your TU report, decreasing your average age more so than on your EX report? If so, this account being removed may have tanked your average age even more.
I recently disputed an account that was removed from both EQ and EX. It was a little over 5 1/2 years old.
I have lotsssssss of accounts on EQ, my score dropped 32 points.
My score dropped only 2 on EX, have lots less accounts on EX.
Nothing different except for the number of accounts. The only thing I can figure out is my average age tanked even worse losing an account that was providing 5 1/2years of history.
The impact was less on EX, because of less accounts, so average age didn't change as much.
