Looks like the radio button white selection dot isn't sticking to the button properly:

And also only one white dot appears at a time.

I was able to reproduce this on Firefox 142 and Chrome 139.0.7258.139 on macOS, with Coder running the latest commit to main.

The buttons themselves still work (i.e. when I go to create the workspace, the right values are used), so this is purely visual.
