How to see one revenue value per month in a Matrix view?

I'm a very novice user of BI and am trying to figure out how to use the Matrix view.

I've created a table for our sales data and would like to display it by state, by month with some other data.

In matrix view, I've put the state and date as the rows, and the sales and other data in the values section.

However in this view the sales data is summed, and I can't find an option to have it display the unique value for that state:month.  The other data in the values section is behaving correctly and displaying per state/month.

Is there a different view I should be using or is my table setup incorrectly?

Thanks!
