New player with missing keys and mastery

I did a task worth 5 keys but they never appeared. then the next task had the 3 blue tokens, so I did that one too. I used the tokens on a purple mastery, and never got the mastery. it took my 3 tokens I used for it. is this common? any way to solve this? my psn is Psycle__ShifT if a dev wants to help.
