Axles legend

I completed axels legend challenges, which usually will unlock her for you to play as, but I logged in after the challenges were unavailable/ completed to see that it not saying I unlocked her. This hasn’t ever happened to me so I’m kind of confused.. I would really rather not have to spend legend token buying her when I just bought Loba thinking I didn’t have to buy axle. If anyone can help me it would be much appreciated.
