I started learning Animal Husbandry with the Glitch HQ app, then later paused it on the website so I could learn Better Learning 3 first. Checking the app later, I saw the progress bar for Better Learning was shown on the "profile" screen, but on the "Skills" screen it was still counting down Animal Husbandry. When the countdown clock for AH was "done," it was replaced with Better Learning 3 on the "Skills" screen. I didn't actually learn AH yet, and it now shows in the skills list with the pause icon next to it.
