Shading in Headings & Column Breaks

[Writer@Large]

I have text at the top of a column that I want to add shading to (a Heading 2
style w/ shading). But whenever I do it, it adds the shading to the column
break before it, too! It's so frustrating! I cannot get it to stop. How do
I go about fixing this, and why would it do this by default?

Before the heading in the column following the break, insert a blank
paragraph (by pressing Enter). Then format a paragraph style as font size 1
pt, spacing before/after zero, line spacing exactly 1 pt, and apply it to
the blank paragraph inserted.
