I am connected to my bank account, but my transactions from last year are not visible. The ones from 2 years ago and the ones from this year are there. Why is that?

Using quickbooks single user. I reconnected by bank account after a long time. it showed transactions from 2 years ago to classify. I did that. I do not see transactions from last year. is there a limit to the number of transactions? why are last year's transactions not showing?
