Would you expect “Headings / Body Text” to control all three typography sliders?

I’m building Unshift, a visual website editor. The screenshot shows our actual typography panel beside Saltbox, a fictional cooking-school demo. The Headings / Body Text switch changes which text the Size, Line Height and Letter Spacing sliders affect. Would you expect that switch to apply to all three sliders? What wording or layout would make that clearer? No-signup demo: playground.unshift.ai
