Pluto’s Surface Has Changed Over Time
A newly discovered mountain range lies near the southwestern margin of Pluto’s Tombaugh Regio (Tombaugh Region), situated between bright, icy plains and dark, heavily-cratered terrain. This image was acquired by New Horizons’ Long Range Reconnaissance Imager (LORRI) on July 14, 2015 from a distance of 48,000 miles (77,000 kilometers) and received on Earth on July 20. Features as small as a half-mile (1 kilometer) across are visible. Courtesy NASA/JHUAPL/SWRI
So, Pluto has a second set of mountains along one edge of Tombaugh Regio (the heart-shaped region).

I can’t say I’m totally surprised to see them; I remember a geology teacher once saying where there’s one mountain range on a world, shaped by some kind of internal process, there’s bound to be another.
