Yes, this is a bit tricky.

The text entry field adds line spaces automatically when you place a return between lines. The bullet point button is actually creating tags around nothing, providing a bullet with no text next to it.

To fix it, simply delete the extra bullet code, which will look like this: <li></li>

In the future, remove all line spaces before highlighting your bulleted items and pressing the bullet button. Entries should begin like this...

entry1
entry2
entry3

to render like this:

• entry1
• entry2
• entry3
