Bullet list not getting properly generated in PDF

Hello,

My jupyter notebook contains a markdown with a bullet list:
```Markdown
Some text here:
 - Item 1.
 - Item 2.
 - Item 3.
```

When I generate the PDF using `jupyter-nbconvert jn.ipynb --to pdf`, the result is:
```
Some text here: - Item 1. - Item 2. - Item 3.
```

Is there are way for nbconvert to correctly generate a nice bullet list?
Thank you!
