Not receiving tokens for missions [Client]

Title says it all. Not a huge fan of Nexus blitz but I want to get tokens for champion shards to turn into BE. The mission was "win your round in prize fight 2 times." It went away and was replaced with "win your round in prize fight 8 times." It's pretty upsetting when I complete a mission and don't receive my tokens. Is there a fix?

I remember also watching a live worlds series all the way through and never receiving rewards for another event.

Also would like if there was a way to get these tokens if you don't want to play Nexus blitz, but hey I'll play it for now I guess if I get rewards (sometimes).

I'd honestly be happy if someone wired me the 6 tokens I got for completing the mission T_T
