As I mentioned I was un sure how payment breaks are reported so thank you for clarification, my reading of the link suggests they shouldn't be but I also took from the info that a lender can infer from loan balance such a payment Break existed without one being specifically mentioned. I'm not entirely sure however why arrears are showing if they are?
It's not clear if OP has seen the credit report or if they were just told the payment Break was reported along with Arrears if they have not requested one perhaps it might be wise to request one just to verify what it actually says or doesn't say. If as OP says, loan was extended how or is that reported, I guess is another question.
