Hello @manninwind, thank you for reporting this to us!
We are not able to replicate the bug. It seems that there might be an issue with your iCloud, is your phone signed in to iCloud and verified?
Would you upload a screenshot of your Favorites so we can try to replicate it with the ones you have added to Favorites?
I was experiencing the similar issue and as you mentioned my issue was with iCloud. Verifying it fixed the issue.
