How to sort layered navigation items alphabetically and numerically

In my layered navigation, I have items that are being sorted by quantity. For example the items with the most quantity are listed higher, and lower quantity are listed lower. What i am looking for

Category
A (2)
B (32)
C (1)

what in currently getting is

Category
B (32)
A (2)
C (1)

I cannot find where or how to change the sorting to be alphabetical/numerical order.
