the 2 attached screen grabs clearly show for both OLS and Arima that the options for the
CI are greyed out with effectively a default to range bars.
The "range bars" only situation is supposed to arise when only a
single forecast is possible. Could you try running the following
script and see what you get in the forecast dialog, please?
nulldata 50
set seed 654321
setobs 1 1975 --time
series u = normal()
series y = 5
y = 0.5*y(-1) + u + 0.2*u(-1)
smpl ; 2012
arma 1 1 ; y -w
