What you have written is UL tag containing OL tags which isn’t correct,
It should be OL tag containing Li tags or UL tag containing Li tags.
The OL is working fine and it should display the numbers correctly,
but there’s an issue with UL it’s not displaying the bullets at the moment, we have fixed it and will release in the next version.
Please try editing your code and let me know whether the problem will be fixed or not .
Thank you ,
