The amount listed is correct, but surveys from that provider may have varying payouts. This is indicated when you click on surveys from this provider:
This survey is routed. This means that if you do not qualify for this particular survey, you may be given the opportunity to take another survey from the same partner that you are more likely to qualify for. The payout of this survey may be different and will be determined by the length of the survey.
We have a few minor glitches here and there with the sorting. I have also noticed a couple of things out of order from time to time when sorting by name as well.
