Student cannot take course after paying

Problem: Student cannot take course after paying for a flat rate course or subscription course. For flat price courses: It looks like the "Subscription Duration" in the product is not being set from the course. Course is associated with a product, and product is associated with course. If I change this setting manually in the backend, then the student can start the course after purchase. However, this was working fine before. https://gyazo.com/7b47a628c77d9532e523c6c9af167d4f For subscription courses: Nothing seems to work.

I'm using Strip test mode, so feel free to try a test purchase.
