Hi ecdj , we thought your issue was resolved. Apologies about that!
Do you have a website where I can look at your buttons? Also, did you copy the button or the group? While I'm thinking about it and after some tests, it seems that the single button styling is saving into the group.
So when you only duplicate a button, it won't duplicate those group settings, only the button one. Could you confirm you've duplicated the button instead of the group in your situation?
Let me know 🙂
