Blog head doesn't show 1st blog

I’m having trouble with duplicate blog heads.

I added this code from a previous query:
.single h1.title { display: none !important; }

This works fine on all the blog pages except the most recent blog entry:

Doesn’t show:
deanenettles.com/resourcepoint/va-spousal-support-calculators-available-for-mobiletablets

Shows:
deanenettles.com/resourcepoint/va-spousal-support-calculator

Is there a specific css class or id that would hit one and not the other?
I haven’t been able to find one.
