A reprex would be helpful.
What versions of R and {forecast} were you using before? What version of R are you using now? I am using R 4.1 and {forecast} 8.15 on MacOS Big Sur.
Which two elements did you get? I got a list of all 10, and it prints "Point Forecast", "Lo 80", "Hi 80", "Lo 95" and "Hi 95".
I have completely transitioned from {forecast} to the tidyverts set of packages ({fable}, {fabletools}, {feasts}, ...) and have not followed any changes to {forecast} so cannot be of too much help.
