Odd notification sound squeak or chirp since 6.1 update

Since updating my Watch to 6.1, my notification sounds are varied. It used to always just be a "ding" or something similar and now it's not. The notification for certain things comes in as a tiny squeak or it sounds a little bit like a bird chirp. The notifications for text messages is still a ding and other notifications are the same. I've already checked the 6.1 update notes, restarted my phone, force restarted my Watch, repaired my Watch, checked online forums, and haven't seen anything about a weird squeak or chirp. I'm not sure if it's just a new feature from the update or if something is legitimately wrong with my watch. Any ideas? Thanks.
