More info is needed.
The date of first delinquency is not always the date of first delinquency under the account, it can be reset if a delinquent debt is paid back into good standing, and a new first delinquency then occurs.
It is the first delinquency in the most recent chain of account delinquency that immediately preceded a reported charge-off or collection.
What is the total payment history?
If it is inaccurate, they can update so as to overcome any inaccuracy.
It wont require deletion of the collection, but is important to get corrected, as the DOFD is the date used by the CRA to calculate the eventual credit report exclusion date of the collection.
