Why is there a difference between real balance and the results in reports:banking cash flow?

I use the Quicke starter 33.7 version Canada with win-10.
Each time i ask for a report in cash flow, appears a difference between my Quicken journal and the result.
Also, each time I ask for a reconcile with my banking trnsactions downloadded, I have to make an adjustment. It was not so in 2020 version and older.
