How do you unlock Rathalos Extreme? The Great Hunt.

How do you unlock The Great Hunt Extreme? I did the regular version and when I talked to the guy he mentioned there was an even stronger dragon ie the Extreme mode but there's nothing listed in my duty finder. I was just in game talking to another person with the same problem. Am I mising something? I've gone back to the two guys who had the original quest but there's nothing there just the merchant where I can buy stuff. What am I supposed to do in order to unlock this? Any help would be much appreciated. Thank you.

Look at the high end duty.

Oh, thank you so much. I checked that but I didn't notice the little Trial Icon so all I was seeing was Sigmascape SAvage. Don't know how I missed that. Thank you so much. /Bow
