Why JMP stores simple moving average forecast for n+1 period in nth period?

Why JMP stores simple moving average forecast for n+1 period in nth period? For e.g I calculated SMA for 7 periods. I want forecast to appear in 8th row but it is appearing in 7th row.Screenshot 2022-09-11 at 14.21.33.png

SMA is not a statistical forecasting method per se. But you can shift the column using the Lag function. Right click on the SMA(7) column and following the menu trail in this screenshot to get the desired result:
