Not receiving reward from Alp Du Zwift completion

I’m new to Zwift and have only completed Alp Du Zwift 3 times now. The first time I completed it I got the reward and received the gloves, not what I was after but that’s okay. The second time I completed I received no rewards at all as the “wheel of fortune” as it where did not pop up. I have now completed it for a third time today and yet again the “fortune wheel” did not pop up on my screen and therefore did not receive a reward again…

Any thoughts as to why this is happening ??
