Confused about track widths. bug?

For the life of me I can’t figure out how I’m supposed to select track widths. As you can see in the first screen, I have two widths defined in design rules. However, as you can see in the second screen, there is only one track width available in the drop-down menu in the top left corner of the screen. Similarly, only one is available in the select track width dialog.

How is this supposed to work? How do I get the other widths to show up so I can select them?

I have been able to make tracks of different widths by doing that, but the widths do not show up in either the right-click context menu or the drop down menu. I can’t change width without reassigning the net class.

Custom sizes is exactly what I was missing. Thanks!
