Neevo, got paid for the newer task but not the older ones?

So I'm a new Neevo member, I did like $50+ worth of tasks. About a week later the indian-english speech thing came up. I did about 100 before i gave up because it wasn't worth my time. Yet i got paid the next day (About $1) for that task, but the other ones that closed earlier in the week ($50+)...still not paid yet?
