GSTR 9 DIFFERENCE BETWEEN ITEM A IN TABLE 8 AND GSTR 2A

WHILE PREPARING GST ANNUAL RETURN UNDER GSTR 9, ITEM A IN TABLE 8, WHICH IS SUPPOSED TO AUTOPOPULATE GSTR 2A VALUE DOESNT AUTOPOPULATE THE CORRECT VALUE AS A SUM TOTAL OF ACUTAL GSTR 2A  VALUES?

I MEAN, THERE'S A DIFFERENCE BETWEEN GSTR 2A TOTAL AND TABLE 8.A. VALUE IN GSTR. IT'S SUPPOSED TO BE SAME. RIGHT?

WE USE COMPUTAX SOFTWARE FOR PREPARING GSTR 9. CAN SOMEONE TELL WHY DOES THE DIFFERENCE ARISE?
