Nested lists do not start new counting

When inserting nested lists, a new nested list should start a new count. As you can see in the image, the second nested list should start again with "a". In the HTML code you can see that it doesn't create a new nested list but a list with an indent class: `

1. La la al a
2. Ba ba ba
3. Foo
4. Bar
5. Sa sa sa
6. Tim
