Missing content in 0.30

After upgrading Hugo on the Mac via HomeBrew to 0.30 I don’t see all the content in the “content/showcase”

    {{ range where (where $.Site.Pages "Section" "showcase") "Draft" false }}
    {{ .Render "showcase-card" }}
    {{ end }}

I’ve gone through and changed some of the dates that are intentionally in 2018 to past dates, but that didn’t seem to matter. I tried to disable fast render, but the option wasn’t supported.

What else should I try?
