Squares with rounded corners

I am using Easel pro and I need to learn how to draw a square with rounded corners. I’ve seen examples where on the shapes selection you can select round corners from a drop box. My version of Easel Pro doesn’t have that drop down selection. I’m at a standstill until I can figure this out.
Thank you all.

This doesn’t show up in Easel Pro?

Thats where it is. Thank you!
