Royalties Tab: Why is my graph going up but I've earned less this quarter?

There are two views available - cumulative earnings + earnings by period. If 'Cumulative Earnings' is selected, you will see a rise in royalties at each data point as your total amount of royalties has increased since the last distribution

In 'Earnings By Period' you will see a different chart which shows the total amount of royalties from each specific statement date.
