Hi Aimee,
This is a known issue, and one we are working to resolve. In the meantime, the workaround is to make the text object with bullets WYSIWYG. You can do this on a per-object basis by selecting the text object and going to the Properties, or on the entire lesson by going to Edit > Lesson Settings.
More info can be found on the
Help page here.
Hope that helps!
