I’m having a similar issues. I am not allowed to claim the level 40 Premium reward at all. I reached level 40 and was able to claim the Barella card, but i am unable to claim the Premium reward. The only information the game is showing me is a Multi Choice Reward Preview. It says i require “0 SP to Unlock” but does not allow me to choose either of the options. Every other reward had the little yellow gift icon over the reward. Level 40 for the premium reward never showed the yellow gift icon for me to claim. Is there a way to claim the Zola card? To be clear, i did not even claim the 10 84+ pack. The game never gave me the option to claim either reward
