Paragraph shading and rules are outside of box

I'm sure there's a simple solution to this, but I've tried everything I can think of.

If a paragraph has shading or a rule, it's appearing above the edge of the text box. I've tried adjusting the baseline shift, adjusting offsets, changing whether or not it aligns to baseline.

What am I missing? I need the lines and the shading to line up with the top of the textbox. (relearning InDesign after 14 years is a challenge!)
