Welments Basics

I dont typically use weldments, but I am working on a (non-product related) project and thought it might be useful. I created my sketch, selected add structural member, standard: ansi inch, type: angle iron... but under "size" only 3 choices are available and none of them are the size I need. Where are the rest of the sizes? Is this a setting somewhere? Please help. I'm sure there is a simple answer and I am just missing it. Thanks in advance!
