Can these go bad?

I ordered the Birthday Cake/Confetti Cake duo. I LOVE Treat Beauty's lip balms and I LOVE the Birthday Cake lip balm....BUT the Confetti Cake smells and tastes like rancid, old cooking grease. This isnt the norm for Treat Beauty products so I'm wondering if its possible for these balms to become rancid? I have multiple scents/flavors and I'be never smelled something this bad in a lip balm ever.
