While making a character everything looks as though it has gone through correctly, but when i look at the final character sheet instead of seeing my "Great Weapon Fighting" i can only see "two weapon fighting" this still also happens if i change the class. 

I have also deleted and restarted the character but it is still showing up on the final character sheet.

Any ideas?

Any character can do two-weapon fighting.

Great weapon fighting is found in the class feature.

thanks
