I was having trouble with fortnite recognizing the joystick, plus the new angle button does not work at all.
1 make sure lock input device as mouse is on and ignore game pad is off (see screen shot)
2 exit fortnite and unplug Azeron controller
3 restart PC then plug the Azeron back in, open Azeron software make sure your stick is set as Xbox 360
4 run fortnite, you should be good to go.
On a side note if you play fortnite a lot I would highly recommend getting reWASD
Additional perks of reWASD:
Macro Controller with "Key Combo", add Turbo button or Toggle some key with "Rapid Fire" and switch controls with "Advanced Mapping". a powerful combo editor — the feature to create various macros, Long Press, Double Press, Shift mode — the ability to add up to 4 different layouts that are activated when a chosen button is pressed, held or toggled. There is no better controller software on earth you will never look back
